Comment(by hiviah):

 Using vanilla gcc 4.4.6 on EL5 works around this bug. Suggested solution
 would be to package the gcc for EL5, put it in a temporary repo, so that
 `mock` will use it when building (until there is a proper fix).

 Submitted to RedHat's bugzilla -
 https://bugzilla.redhat.com/show_bug.cgi?id=901750

 Note to self on building gcc 4.4.6 (so that I don't forget later):

 - http://gcc.gnu.org/wiki/FAQ#configure (non-trivial configuration)
 - glibc-devel.i386 must be installed on x86_64 machine, build fails
 otherwise
 - configure must be run in separate dir than unpacked source, otherwise
 build fails; see invocation below
 - remove gmp-devel and any libmpfr.(so|a) lying around, it will confuse
 the gcc build scripts and break whole thing upon linking

 {{{
 ../gcc-4.4.6/configure \
   --with-mpfr-include=/usr/local/include \
   --with-mpfr-lib=/usr/local/lib \
   --with-mpc-include=/usr/local/include \
   --with-mpc-lib=/usr/local/lib \
   --with-gmp-include=/usr/local/include \
   --with-gmp-lib=/usr/local/lib \
   --enable-languages=c
 }}}
