           Summary: Workers + garbage collector: weird crashes
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2

I want to run SunSpider in multiple threads to explore the benefits of multi
core systems. To accomplish this task I decided to put the whole SunSpider into
a Worker thread. Unfortunately, I got weird crashes here:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread -1278313552 (LWP 1285)]
0xb733c000 in JSC::Heap::markConservatively () from
/home/hzoli/Webkit-ARM/WebKit-arm/WebKitBuild/Release/lib/libQtWebKit.so.4

I think it is related to the Garbage Collector. The crashes are random events,
sometimes the script run successfully, but it is always in function
markConservatively.
