Type pm_arrayRebind::setRebound

Status: Unresolved
Source: GNU Fortran Compiler gfortran version 10-12
Description: There is an annoying gfortran bug concerning allocation of allocatable arrays of strings with assumed length type parameter.
The typical compiler error message is around line 230: Error allocating 283223642230368 bytes: Cannot allocate memory.
This requires the allocation statement be explicit for character arrays of non-zero rank.
This makes the already complex code superbly more complex and messy.

Remedy (as of ParaMonte Library version 2.0.0): For now, the allocatable arrays of type character are allocated with explicit shape in the allocation statement.
This explicit allocation for character types must be removed and replaced with the generic allocation once the bug is resolved.

Status: Unresolved
Source: Intel Classic Fortran Compiler ifort version 2021-2022
Description: There is an Intel compiler 2020-2022 bug in processing multiple CHECK_ASSERTION macros in individual routines of this module in debug compile mode.
The problem does not appear to exist in other compilation modes.
However, this bug does seem to be related to other similar instances where Intel Classic Fortran Compiler ifort cannot tolerate frequent appearance of use statements within a single submodule.

Remedy (as of ParaMonte Library version 2.0.0): For now, the resolution was to remove and replace the checking macros with explicit merged block statements.
A similar problem also was present in the implementation of pm_quadPack.

Description: The Intel Classic Fortran Compiler ifort returns a runtime error in Microsoft WSL,


Status: Unresolved
Source: GNU Fortran Compiler gfortran version < 12
Description: The GNU Fortran Compiler gfortran cannot compile interfaces with dummy arguments character(:), intent(out), allocatable, optional.
This has created a redundancy for error handling in this procedure by requiring also to pass iostat to control the occurrence of an error.
Without this bug, the allocation status of iomsg could have been used to signal no occurrence of error.

Remedy (as of ParaMonte Library version 2.0.0): All iomsg arguments are now assumed-length strings.

Type pm_matrixInit::getMatInit

Status: Unresolved
Source: Intel Classic Fortran Compiler ifort version 2021.8.0 20221119
Description: Intel Classic Fortran Compiler ifort thows a strange error for compiling this module when dia constant is used within this module.
Apparently, Intel Classic Fortran Compiler ifort confuses this imported constant with the dummy procedure argument of the same type in procedures named getMatInitXXD_D2XX0* or getMatInitXXD_D2XX1.

Remedy (as of ParaMonte Library version 2.0.0): There does not appear to exist any way to resolve this intel error currently, other than not importing the constant dia in this module.
Instead, one has to use dia_type() to call the procedures when resolving the generic interface.
As such, the argument names upp, low, dia were renamed to vupp, vlow, vdia to emphasize the value attribute of these arguments and to resolve the Intel name-conflict bug.
Type pm_quadTest::test_isFailedQuad

For example, gfortran fails to compile the following submodule procedure interface,
For example, gfortran returns the following error code,
Module pm_sampleCov

Status: See Unresolved, See this page for more information.

Source: GNU Fortran Compiler gfortran
Description: Ideally, there should be only one generic interface in this module for computing the biased/corrected/weighted variance.
This requires ability to resolve the different weight types, which requires custom derived types for weights.
Fortran PDTs are ideal for such use cases. However, the implementation of PDTs is far from complete in GNU Fortran Compiler gfortran.

Remedy (as of ParaMonte Library version 2.0.0): Given that the importance of GNU Fortran Compiler gfortran support, separate generic interfaces were instead developed for different sample weight types.
Once the GNU Fortran Compiler gfortran PDT bugs are resolved, the getVar generic interface can be extended to serve as a high-level wrapper for the weight-specific generic interfaces in this module.
Type pm_sampleCov::getCov

Status: Unresolved
Source: Intel Classic Fortran Compiler ifort version 2021.8
Description: Intel ifort (possibly only with heap memory allocation) yields a segfault error in OpenMP parallel code at pm_sampleCov@routines.inc.F90:238.
The root cause of the segmentation fault was determined to be due to the use of do concurrent construct in the implementation.

Remedy (as of ParaMonte Library version 2.0.0): For now, all do concurrent statements are converted back to normal do loops.

Source: GNU Fortran Compiler gfortran version 10-12
Description: The character ESC should be ideally and portably defined as achar(27, kind).
However, GNU Fortran Compiler gfortran as of version 11 cannot handle this in component initializations.

Remedy (as of ParaMonte Library version 2.0.0): The character ESC is defined a direct copy of the actual character via a preprocessor macro.
