[Octave-bug-tracker] [bug #62207] segfault in bug-35881/bug-35881.tst in 32-bit ARM and MIPS

[John W. Eaton]

Follow-up Comment #56, bug #62207 (project octave):

This one is weird because line 3842 in pt-eval.cc is a "throw;" statement to
rethrow the exception that was just caught and without even any modification. 
So I don't see how that is generating a "stack use after scope" error.
