Sorry for the late response. I don't know much about Fortran or
gfortran, but I tried to have a look at the failure. More details below,
but unfortunately I didn't find anything concrete. Hopefully the Valgrind
reports can help.
Please let me know if there are other tests or investigation I can make.

I can see the problem reliably when running the testcase binary for -O1
on an armv8l-linux-gnueabihf machine. Here's a GDB session showing where
it abruptly exits:
$ gdb -q class_transformational_2.exe

(gdb)
If I step into reshape, things seem to work fine, all the way to
_gfortrani_reshape_packed. If I then type "next" after the last
statement in that function, the process ends:
_gfortrani_reshape_packed (ret=0x252e0 "", rsize=128, source=0x25258
"\001\001\001\001", ssize=128, pad=0x0, psize=8) at

(gdb) n
42 while (rsize > 0)
(gdb) n
STOP 12
[Inferior 1 (process 3739928) exited with code 014]
(gdb)
If instead of typing "next", I type "step", then GDB enters realloc, and
some "MAIN__::__copy_MAIN___S" thing before moving to the next
line. Then it actually leaves the line with the reshape call and
proceeds further! It ends up exiting within check_result, line 48:
⋮
48 if (any (a%i .ne. ii)) stop stop_flag + 2
(gdb)
STOP 12
[Inferior 1 (process 3739974) exited with code 014]
(gdb)
So this seems to be a heisenbug, where the program behaves differently
in the presence of a debugger...
Just some baseless speculation: maybe the realloc call is failing? And
for some unknown reason, when doing the single-stepping in GDB it
succeeds? I can't think of anything else at least so far.
For comparison, here are sessions on a binary built with -O0:
$ gdb -q class_transformational_2-O0.exe

(gdb) break check_spread

(gdb)
Note that 'c' is very different than in the -O1 case. Is that expected?
Now with a binary built with -O2:
$ gdb -q class_transformational_2-O2.exe

(gdb)
Here, 'c' is the same as in the -O1 case.
If I run the "continue" GDB command, then the program completes
successfully. I wasn't able to break on check_spread this time because
that function isn't present in the optimized binary.
Another thing that I noticed is that the test occasionaly fails on
aarch64-linux, about 1 in 50 times when I run it repeatedly in a
loop. This happens with the "-O1", "-O2", "-O3" and "-O3
-fomit-frame-pointer -funroll-loops -fpeel-loops -ftracer
-finline-functions" variations. But not with the "-O0" variation.
Because the failure is intermittent, I wasn't able to run a debugger
when it happens yet. I'll try again next week with some scripting.
I tried reproducing on x86_64-linux, but couldn't.
I'm attaching the valgrind reports for arm and aarch64.
