| Subject: | AS 5.8.9 x86 segfaults with threads and XS implementation |
The XS implementation of B::H::EOS segfaults under at least AS 5.8.9 x86. Very similar to bug RT#82922.
https://github.com/bobtfish/b-hooks-endofscope/pull/2 contains tests to test this.
This can be worked around by the user by setting $ENV{B_HOOKS_ENDOFSCOPE_IMPLEMENTATION} to 'PP' to force the use of B::H::EOS::PP.
Set up gcc environment - 3.4.5 (mingw-vista special r3)
