[ruby-core:50362] [ruby-trunk - Bug #7456] Build failure with x64 mingw on Windows 8

Issue #7456 has been updated by h.shirosaki (Hiroshi Shirosaki).


When iseqv is 0 at ADD_CATCH_ENTRY in compile.c, invalid VALUE (higher bits over 32bit are non zero) is added to iseq->compile_data->catch_table_ary.
This causes Segmentation fault in GC mark phase.

Since rb_ary_new3() has variable arguments, proper cast of arguments would be needed.
I confirmed build completes with this patch on Win8 release preview running on VM, but I don't have Win8.

1.9.3 also have this code.

Whereas, Ruby 1.9.3p327 succeed to build with x64 mingw.
And Trunk build with VC 2012 64bit is also successful.
