--- Comment #2 from Zan Dobersek <zan at falconsigh.net> ---
In debug build, a probably relevant assert is hit:

ASSERTION FAILED: !(reinterpret_cast<intptr_t>(to) & 1)
../Source/JavaScriptCore/assembler/ARMv7Assembler.h(2205) : static void JSC::ARMv7Assembler::relinkJump(void*, void*)
1   0x7408650e WTFCrash
2   0x729b6bd2 JSC::ARMv7Assembler::relinkJump(void*, void*)
3   0x729dbc32 JSC::AbstractMacroAssembler<JSC::ARMv7Assembler, JSC::MacroAssemblerARMv7>::repatchNearCall(JSC::CodeLocationNearCall, JSC::CodeLocationLabel)
