Description of problem: Since the upgrade to GCC 5.0 I have been unable to build webkitgtk4. It fails on ARM:

/builddir/build/BUILD/webkitgtk-2.7.4/Source/JavaScriptCore/bytecode/Watchpoint.h:49:7: internal compiler error: Segmentation fault
 class StringFireDetail : public FireDetail {
       ^

Version-Release number of selected component (if applicable): 5.0.0-0.9.fc22


How reproducible: Always


Steps to Reproduce:

If you don't have an ARM machine handy:

1. Grab srpm from koji: https://kojipkgs.fedoraproject.org//work/tasks/2969/8892969/webkitgtk4-2.7.4-6.fc22.src.rpm
2. scp webkitgtk4-2.7.4-5.fc22.src.rpm arm03-packager00.cloud.fedoraproject.org:
3. ssh arm03-packager00.cloud.fedoraproject.org (all packagers have access to this)
4. If need be: 'sudo usermod -a -G mock yourusername', exit, reconnect
5. mock --rebuild webkitgtk4-2.7.4-5.fc22.src.rpm --no-cleanup-after -r fedora-rawhide-armhfp

(I actually tested with a slightly different SRPM but the crash is the same.)

Actual results: GCC crashes


Expected results: No GCC crash
