There are 27 jsc test (run-javascriptcore-tests) crashes
and more than 100 layout test crashes on 35 bit platforms,
for example Qt Linux 32 bit and Qt ARM buildbots:
- http://build.webkit.sed.hu/builders/x86-32%20Linux%20Qt%20Debug/builds/26627
- http://build.webkit.sed.hu/builders/ARMv7%20Linux%20Qt5%20Release%20%28Test%29/builds/9112

I'll upload gdb backtraces soon.
