JSC is reported to crash when opening this URL: http://gexpertise.fr/activites/metiers/stockage

This has been reproduced with the MiniBrowser in 2.12.1, but Carlos reports that 2.12.2 crashes as well. trunk seems to be working fine.

A workaround is to set JavaScriptCoreUseJIT=0

Here's the backtrace:
