Pre-processed source for stress-vecmath.c
Hi!
When building stress-ng on powerpc-linux-gnuspe, an internal compiler error
occurs when compiling stress-vecmath.c:
cc -g -O2 -fstack-protector-strong -Wformat -Werror=format-security -Wall
-Wextra -DVERSION="0.06.01" -O2 -DHAVE_APPARMOR -DHAVE_KEYUTILS_H

Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
See <file:///usr/share/doc/gcc-5/README.Bugs> for instructions.
Preprocessed source stored into /tmp/ccRHm88P.out file, please attach this to
your bugreport.
This has been failing for quite some time. However, it seems it does not seem
to be related to gcc directly as both the last successful build [1] and the
last unsuccessful build [2] used both the same revision of gcc-4.9.2: r218987.
Attaching the pre-processed source from the last build with gcc-5.
