[Bug target/57982] GetModuleHandle in __register_frame_info causes abort on unload
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=57982 --- Comment #3 from Kai Tietz ktietz at gcc dot gnu.org --- The problem here is the use of weak on pe-coff. The change you see on gcc is just addressing the fact that for 64-bit the weak symbol never can get 0 due relocation-limitations. We try to address this. On the other hand we have here to work-a-round a binutils quirk that default-implementation of a weak is used in its definition TU always, even if a none-weak symbol is present in a different TU. This can be worked-a-round by moving default-implementation into different TU. Hope this answered some of your questions. (anyway IMHO, in general we should have used here a variant without any weak-symbol)

Issue fixed for 4.7, 4.8, and trunk at rev 204635-204637. I recently stumbled on a similar problem again with a recent Cygwin/GCC combination. Looking at the fix included in GCC, it does look slightly different from what was first suggested here. Could someone more knowledgeable than me have a look and tell whether the included fix is fine or incomplete? If incomplete, I'll be happy to open a new bug report.
