Comment # 3 on bug 1061204 from Wolfgang Rosenauer

I'm not totally sure actually so it could be toolchain (packaging) related but
compiler flags are just
export OPT_FLAGS="%{optflags} -fno-strict-aliasing"

which seems to lead to compiler flags used like:
-fomit-frame-pointer -fmessage-length=0 -grecord-gcc-switches -O2 -Wall
-D_FORTIFY_SOURCE=2 -fstack-protector -funwind-tables
-fasynchronous-unwind-tables -g -fno-strict-aliasing -fPIC -Di386  -pipe
-ffunction-sections -fdata-sections

So I have little indication that this is related to packaging but I will
obviously follup up any upstream bug regarding this if it turns out build
dependent.
