Source: gf2x Version: 1.1-2 Severity: serious Control: affects -1 src:sagemath
A FTBFS in sagemath boiled down to gf2x violating the amd64 baseline by building with "-msse2 -msse3 -mssse3 -msse4.1 -mpclmul". The same problem exists on i386 with "-msse2 -msse3 -mssse3". gf2x 1.1-2 has similar problems by building with "-msse2 -mpclmul" if supported during the build, and building with "-msse2" on i386. gf2x must not ever set any of these flags (-msse2 on amd64 is harmless since it is already enabled by default, but therefore also pointless).
