            Bug ID: 38616
           Summary: Wine 1.7.43 (32-bit) cannot be built by GCC 4.3.2 with
                    -O3 flag.
           Product: Wine
           Version: 1.7.43
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ntdll

GCC error message

GCC 4.3.2 with the optimization flag -O3 (and also -O2 or -O1) cannot 
compile 32-bit Wine 1.7.43. An error is occured in "dlls/ntdll/server.c":

server.c: In function 'server_get_unix_fd':
server.c:971: error: unable to find a register to spill in class
'GENERAL_REGS'.

The full text of the error message is in the attachment. This is not an issue 
for Wine 1.7.42 and I found that the regression is caused by the commit

commit 40c912b4bef45099d465ddb9a7cb16f33ec4ed3c
Author:: Sebastian Lackner <sebastian(a)fds-team.de>

 ntdll: Use lockfree implementation for get_cached_fd.

If the optimization level is set to -O0 only for "dlls/ntdll/server.c" 
(by manual editing of "dlls/ntdll/Makefile"), the process of compilation 
completes successfully. Optimization flags other than -O do not affect 
the result.

GCC version is 4.3.2 (my system is Fedora 10). Wine is configured with 
CFLAGS="-mtune=amdfam10 -march=amdfam10 -mfpmath=sse -O3 -ffast-math -msse3
-funroll-all-loops".

This bug should be filed against GCC, although they will probably want you to
upgrade to the latest version and try again (in case it was already fixed).

This line from your attachment:
> Preprocessed source stored into /tmp/ccPIMOdr.out file, please attach this to your bugreport.

is coming from GCC and is suggesting that you need to include that file with
your bug report to the GCC project.

I cannot reproduce this bug, so its probably already fixed in newer gcc
versions. Tested with:

$ gcc --version
gcc (GCC) 4.9.2 20150304 (prerelease)

*UPSTREAM.

Closing, as it's fixed in newer GCC.
