After upgrading to GCC 4.4.0-r1 and recompiling the system with -O3 -march=barcelona a number of packages got broken. Wine used to work with these flags, but doesn't any more. I have confirmed that wine-1.1.20, wine-1.1.25 and wine-1.1.26 stop working with the error below if compiled using GCC 4.4.0-r1 but work perfectly fine if compiled using GCC-4.3.3-r2. The compilation itself goes smoothly and without any problems, but the binaries are useless -- they still work in the sense that they are capable of producing an error, but simply won't be able to run any program. I am setting severity to major because it might be that there is either a subtle but important bug in GCC or something weird happens in Wine. Reproducible: Always Steps to Reproduce: 1. emerge wine with gcc 4.4.0-r1 using CFLAGS -O3 -march=barcelona, but I guess any AMD64 MARCH would work 2. run something under wine (example below: EditPlus 3.11) Actual Results: wine: Unhandled page fault on read access to 0xffffffff at address 0x7ecef934 (thread 0027), starting debugger... Unhandled exception: page fault on read access to 0xffffffff in 32-bit code (0x7ecef934).

As an additional comment, compiling with GCC 4.4.0-r1 and restricting CFLAGS to -O2 -march=barcelona solves the problem. Maybe some weird optimization flag got included into -O3 that wasn't there before?

I had the same problem as the reporter, and found that adding -fno-tree-vectorize (in addition to -O3) fixed it for me. Alternatively, using -O2 -ftree-vectorize causes it to crash.
restored the strip-flags behind USE=custom-flags
