I have the following two test failures with x64-mingw32 on Windows 7.

$ gcc -v 2>&1 | tail -n1
gcc version 4.8.2 20130712 (prerelease) (Built by MinGW-builds project)
$ make test-all TESTS="-q ruby/test_exception.rb"

I'm not sure the reason, but setting larger stack size fixes SIGSEGV.

Nobu,

Can you review, reject or approve so we can resolve these test failures?

Thank you.

[h.shirosaki (Hiroshi Shirosaki)]

• File 0001-Handle-machine-stack-overflow-on-mingw.patch 0001-Handle-machine-stack-overflow-on-mingw.patch added

I found this fix was provided on mswin at r43748, but not on mingw.

We can use Structured Exception Handling by
Addvectoredexceptionhandler() for machine stack overflow on mingw.
This would be equivalent to the handling using __try and __exept
on mswin introduced by r43748.

Attached a patch.

Interestingly, I met this test error recently on Fedora's builder:

  3) Failure:
