This patch seems to have caused a number of regressions: http://gdb-build.sergiodj.net/builders/Fedora-x86_64-m64/builds/1502 http://gdb-build.sergiodj.net/builders/Fedora-x86_64-m32/builds/1501 http://gdb-build.sergiodj.net/builders/Fedora-i686/builds/1510 (possibly among others) Reverting this patch locally makes the regressions disappear for me, at least on x86_64-m64.
