From what I've heard, there was a bug in the gcc bundled with Xcode
2.3 that caused stack alignment issues when -O2 was used (and maybe -O1?). This is supposed to be fixed in Xcode 2.4, which is what I'm using, yet I'm still getting a "Bus Error" with all default CFLAGS. Adding -O0 into the mix fixes the problem.
Here's all I could gleam with gdb:
Breakpoint 1, NtAllocateVirtualMemory (process=0x7bc5b6f1, ret=0xbffff949, zero_bits=3221222220, size_ptr=0x10000, type=3221222216, protect=2147352576) at virtual.c:1306 1306 in virtual.c (gdb) bt #0 NtAllocateVirtualMemory (process=0x7bc5b6f1, ret=0xbffff949, zero_bits=3221222220, size_ptr=0x10000, type=3221222216, protect=2147352576) at virtual.c:1306 #1 0x7bc4f428 in thread_init () at thread.c:224 #2 0x7bc2beea in __wine_process_init () at loader.c:2354 #3 0x60a088c1 in wine_init (argc=2, argv=0xbffff8b8, error=0xbffff450 "", error_size=1024) at loader.c:664 #4 0x7bf00f2d in main (argc=2, argv=0xbffff8b8) at main.c:58 [stepping...] (gdb) step NtAllocateVirtualMemory (process=0x2001, ret=0xbffff22c, zero_bits=1048576, size_ptr=0x1000, type=4294967295, protect=10514258) at virtual.c:1379 1379 in virtual.c (gdb) print status $22 = 0 [stepping...] (gdb) step thread_init () at thread.c:226 226 thread.c: No such file or directory. in thread.c (gdb) print addr $23 = (void *) 0x7ffde000 (gdb) print size $24 = 4096 (gdb) step 228 in thread.c (gdb) step
