Details:

When executing "__run_test_suite__" with Octave from the default branch on
Windows causes it to crash with a segmentation fault. See the attached
backtraces.
The crash happens at the fixed tests towards the end of the test suite at
different tests that seem to be unrelated. But the backtraces look similar.

The last version that completes the test suite without crashing is hg id
a0079f6f8c4 with 466c405ee09b and ac0b3c09c3db grafted on top.
I am having trouble cross-compiling a lot of the sub-sequent nodes for
Windows. The next version I managed to cross-compile is hg id 14e844f1459a.
That version already shows the segfault.
