Faust built with mingw64 segfaults #1035

Closed Spacechild1 closed 4 months ago

Spacechild1 commented 4 months ago

I've tried to build and install Faust from source with mingw64 (Msys2), but the resulting faust.exe segfaults.

Here's the backtrace from GDB:

Apparently, the segfault happens at static initialization time.

Are you using master-dev head? (there was a recent fix : https://github.com/grame-cncm/faust/commit/08cf4e905fbcec5a2cd454705f317aff87e9b7cb for a crash in a LTO context, but which seems similar to your crash), that is similar to: https://github.com/grame-cncm/faust/issues/1033

I was on the pd-multichannel branch. The current master-dev does work indeed! Thanks!

pd-multichannel has just been rebased on master-dev and pushed (--force), so should be usable also.
