--- Comment #3 from Rich Townsend <townsend at astro dot wisc.edu> ---
I can get the MWE to barf on MacOS/Arm (Sonoma 14.1.1), gfortran 13.1.0, by
changing the length of the character vars in the main program from 64 to 16.
The error is now:

In file 'test.f90', around line 49: Error allocating 211106259502048 bytes:
Cannot allocate memory

Error termination. Backtrace:
#0  0x102d77617
#1  0x102d781b7
#2  0x102d78457
#3  0x10275f5bb
#4  0x10275fc37
#5  0x10275f84f
#6  0x10275fc87

Once again, commenting out the allocate w/ STAT line makes the problem go a=
way.
It seems as though having two allocate invocations (one with stat, one with=
out)
is causing some kind of memory corruption.=
