[Octave-bug-tracker] [bug #57353] crash signal 11 when using patch() with large stl file

[Rik]

Follow-up Comment #25, bug #57353 (project octave):

I'm not the original reporter, but I can verify that this now works for me.

In the original implementation, the variable vec_vn is a local variable in a
function, which means the memory for it comes from the stack.  I used gdb and
the sizeof() operator to find that the size of the variable was 9.6 MB.  In
the shell, I checked with "limit" and the stacksize was 8.192 MB.  Just to
verify, I changed the stacksize in the shell to 10 MB and then the code in
test_patch_v2.m passes.  Clearly, this is the root problem and I agree with
Markus' fix to shift this variable on to the heap.
