Created attachment 194227 [details] Stack trace with method names and arguments. QtWebKit crashes RenderTableSection::paintObject on Windows 64 bit with the MSVC 2012 compiler when optimization is turned on. Turning optimization off for this method prevents the crash. The stack trace and disassembly are attached. The access violation causing the crash happens at "000007F8C066032D mov rcx,qword ptr [rax+r15+8]" in the disassembly. Will make a reduced test case and report to Microsoft with that.
