You're right, I found it on GTK Linux 32-bit Release bot, too.

fast/js/dfg-value-to-int32-with-side-effect-crash-log.txt:

Crash log for DumpRenderTree (pid 17731):

Coredump core-pid_17731-_-process_DumpRenderTree not found. To enable crash logs:

- run this command as super-user: echo "/path/to/coredumps/core-pid_%p-_-process_%e" > /proc/sys/kernel/core_pattern
- enable core dumps: ulimit -c unlimited
- set the WEBKIT_CORE_DUMPS_DIRECTORY environment variable: export WEBKIT_CORE_DUMPS_DIRECTORY=/path/to/coredumps
