            Bug ID: 65761
           Summary: internal compiler error: in patch_jump_insn, at
                    cfgrtl.c:1296
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: gcov-profile
          Assignee: unassigned at gcc dot gnu.org

This happened while building Firefox with PGO with GCC 5.1.0-RC-20150412,
compiled with "--enable-languages=c,c++  --disable-nls
--disable-gnu-unique-object --enable-__cxa_atexit --with-arch-32=pentiumpro".

As it happened on Mozilla automation, though, I don't have more than the build
logs, unfortunately. This happened building a x86 (32-bits) Firefox on a x86-64
host with a x86-64 toolchain.
