Description Patrick McLean gentoo-dev 2004-10-16 15:26:01 UTC 
Compilation of media-libs/tiff-3.6.1-r2 dies with assembler errors when the -ffast-math flag is in CFLAGS, probably should add a "filter-flags -ffast-math" to the ebuild (doing that made it compile).

Reproducible: Always
Steps to Reproduce:

It compiles fine for me with/without -ffast-math.
