--- Comment #4 from Martin Gieseking <martin.gieseking at uos dot de> 2012-11-30 15:56:00 UTC --- Created attachment 28839 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=28839 simplified sample code I simplified the sample code a little bit by removing the static method. The bug seems to occur only in conjunction with polymorphism and multiple inheritance. At least, I wasn't able to provoke it with some simpler construct. So I'm not sure if the failure is actually related to the exception handling model implemented in the compiler, as the code is supposed to not throw any exceptions. As far as I know, mingw64 also uses SjLj, doesn't it? When creating a 64 bit executable with it, it runs correctly. Only the 32 bit binaries show this issue.
