P1: Critical Description
On 64bit machines JSC crashes erratically (in terms of when/where).
On debug builds it's always:
ASSERTION FAILED: offset == static_cast<int32_t>(offset)
(/home/tsenyk/qt/qtGit/src/3rdparty/javascriptcore/JavaScriptCore/assembler/X86Assembler.h:1603 static void QTJSC::X86Assembler::setRel32(void*, void*))
... but the when/where is still erratically.
I seams to happen more often in applications with more memory consume.
