Csaba, finally we got Qt 5.0 webkit release build on ubuntu (32-bit), but it passed the test, even after I made it reportExtraCost(64*1024*1024). Given that the issue cannot be produced on either ubuntu 32-bit or QNX, I tend to suggest it is a platform/port specific GC issue, probably something related to stack walking code, and probably related to 64-bit linux.
