Bug#637182: llvm-gcc-4.5: undefined reference to `memset' error when compiling Wine with optimization (regression)

[Austin English]

Package: llvm-gcc-4.5
Version: 2.9-2
Severity: normal
Tags: upstream

Wine compiles fine with llvm-gcc-4.2.1 (see http://bugs.winehq.org/show_bug.cgi?id=28030), but with llvm-gcc-4.5, it fails to build at loader/preloader.c, when linking:

austin at debian:~/wine-git/loader$ make
llvm-gcc -o wine-preloader -static -nostartfiles -nodefaultlibs -Wl,-Ttext=0x7c400000 preloader.o ../libs/port/libwine_port.a
preloader.o: In function `set_process_name':
/home/austin/wine-git/loader//preloader.c:455: undefined reference to `memset'
preloader.o: In function `map_so_lib':
/home/austin/wine-git/loader//preloader.c:455: undefined reference to `memset'
collect2: ld returned 1 exit status
make: *** [wine-preloader] Error 1

disabling optimizations allows Wine to compile fine (and it runs, unlike in 4.2).

The bug appears when linking, not sure how to get a reduced testcase for that, please advise if needed.

Wine version is 1.3.26.
