Steps to Reproduce:
Rebuild wine source RPM.

I am attaching the preprocessed source output generated by GCC when the compile failed.

The same code compiles correctly on GCC 6.
Comment 1 Michael Cronenworth 2016-02-10 14:21:34 UTC 
I noticed that the preprocessed file compiles without error. The bug is only reproduced when compiling from source. If I compile the preprocessed file Wine is able to finish compiling without error. Is there any additional information required?
Comment 2 Michael Cronenworth 2016-02-11 22:37:36 UTC 
Fedora's default CFLAGS are being used so -O2 is being used.

The code compiles from source with -O1 set. However, "dlls/crypt32/chain.c" fails to compile with -01 and must be compiled with -O0. I can complete a full Wine compile with -O0.
Comment 3 Michael Cronenworth 2016-02-12 03:35:17 UTC 
(In reply to Michael Cronenworth from comment #1)
> I noticed that the preprocessed file compiles without error.

My mistake in not using optimizations in my test.

Reproducible:
gcc -O2 -x c -c wine-gcc-error.pp -o wine.o

Compiles:
gcc -O1 -x c -c wine-gcc-error.pp -o wine.o
Comment 4 Marek Polacek 2016-03-10 14:40:01 UTC 
This was fixed in GCC6 with r232111.  Uros backported this patch to gcc5 branch as well, so this ought to be fixed in the next Fedora gcc5 build.
Comment 5 Michael Cronenworth 2016-04-04 04:52:10 UTC 
It's been a few weeks and there has not been a new gcc 5 build. Is there an ETA? Thanks.
Comment 6 Michael Cronenworth 2016-04-13 23:23:04 UTC 
The latest gcc package fixes this. Thanks.
