Ticket details:
According to Microsoft's GetModulePathNameA() function documentation:
The global variable _pgmptr is automatically initialized to the full path of
the executable file,
and can be used to retrieve the full path name of an executable file.
It appears that this global variable initialization occurs, only if the
run-time start-up code calls Microsoft's getmainargs() function, but that
exhibits defective globbing of wild-card patterns, and MinGW has not used it,
as a default start-up hook, since the release of mingwrt-3.21, in December
2014. Consequently, references to _pgmptr, in code linked against mingwrt-3.21
(and later), are likely to dereference a NULL pointer.
