Are you compiling with -fstack-protector in your CFLAGS?
No. If I'm bisecting I use "-O2 -pipe -ggdb" for Wine-64 and add -mstackrealign for building the Wine-32 side. I use more exotic flags only after I've gotten things to work correctly with more conservative flags. I do an out of tree build starting with empty directories for both sides (32 and 64-bit). If ccache misses a lot it can get slow but I get more reliable builds this way.
