FWIW, I can't reproduce the failure with Debian's gcc 3.4.6.
ISTR this bug was fixed in later 3.4.x versions.

-mno-explicit-relocs will degrade the efficiency of the compiler's
instruction scheduling since some macro expansions are left to the
assembler in that case. It will likely affect both execution speed
and code size.
