when building glibc-2.3.4, with CFLAGS="-O3 -march=pentium-m -mmmx -msse -msse2
-mfpmath=sse" everything is built with no apparent failures but when i run the
elf/ldconfig from the newly built src i get a segv in convert_options()
however, if the CFLAGS have the reference to "-march=pentium-m" and "-msse2"
dropped, a rebuild does not cause elf/ldconfig to segv.
is this a bug in the optimisation for pentium-m?
i have tried adding back "-march=pentium3" and that does not generate a ldconfig
that segvs
glibc that was configure to produce the error was:
CFLAGS="-O3 -march=pentium-m -mmmx -msse -msse2 -mfpmath=sse" \
./glibc-2.3.4/configure --prefix=/usr --sysconfdir=/etc \
--enable-add-ons=nptl --with-tls --with-__thread --enable-bind-now
