Created attachment 345548 [details] build.log for wine-1.5.28 with gcc-4.8.0
This is an old bug, and it can be (temporarily) resolved by changing this line at loader/Makefile.in: wine-preloader wine64-preloader: preloader.o Makefile.in $(CC) -o $@ -static -nostartfiles -nodefaultlibs -Wl,-Ttext=0x7c400000 preloader.o $(LIBPORT) $(LDFLAGS) One need to delete "-nodefaultlibs"
Bug begins his way from LLVM-GCC4.5 at Debian (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=637182). Then it was redirected to Wine Bugtracker (bugs.winehq.org/show_bug.cgi?id=28050), then - to LLVM (http://llvm.org/bugs/show_bug.cgi?id=11172). LLVM fixes it, but GCC has not.
This error is from this gcc bug: https://bugs.gentoo.org/show_bug.cgi?id=461954 Steps: 1) Wine has no memset function in preloader.c at all! It has wld_memset, which is not calling any library functions 2) But. According to the bug above - GCC 4.8 is smart enough to determine, that this function is just memset! 3) So... it changes it to memset. 4) But... There is no memset included in preloader.c. Oops! Error!
Oops. This GCC Bug - http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53081
FYI, all of wine (not just the preloader) is broken due to gcc-4.8.0's memcpy "optimization": http://bugs.winehq.org/show_bug.cgi?id=33307
Just a confirmation: I applied the upstream patch < http://gcc.gnu.org/viewcvs/gcc?view=revision&revision=198321 > to sys-devel/gcc-4.8.0 and compiled wine with "-O2 -pipe -march=native", and seemingly the problem is gone. I tested with my old WINEPREFIX and a new one, with wine and wine64, with notepad and some other apps, with WINEDEBUG=heap and without, nothing visible wrong so far. (Except a few weird "err:module:DelayLoadFailureHook failed to delay load user32.dll.CreateDialogParamW" and "err:module:attach_process_dlls "gdi32.dll" failed to initialize, aborting", but I remember these errors show up with my wine built with gcc-4.7.2 as well and caused no visible issue as far as I could see.) The patch may be all too risky to get merged right now, but could be useful if you really don't want to leave two gcc versions on one system.
It ain't risky if it's committed upstream.
Fixed in 4.8.0 p1.3.
