The following test case (run with -n -a -m) crashes on TI tip, tested on 64 bit: gczeal(2); function complex(aReal, aImag) {} function mandelbrotValueOO (aC, aIterMax) { for (var iter = 0; iter < aIterMax; iter++) { } } function f(trace) { const width = 60; const height = 60; const max_iters = 50; var output = []; for (let img_x = 0; img_x < width; img_x++) { for (let img_y = 0; img_y < height; img_y++) { let C = new complex(-2 + (img_x / width) * 3, -1.5 + (img_y / height) * 3); var res = mandelbrotValueOO(C, max_iters); if (output.length > 0 && complex(5)) { } else { output.push([res, 1]); } } } } var timenonjit = f(false); ==20091== Invalid read of size 2 ==20091== at 0x412F14: JSFunction::isInterpreted() const (jsfun.h:150) ==20091== by 0x412F41: JSFunction::script() const (jsfun.h:223) ==20091== by 0x4131D1: JSStackFrame::script() const (jsinterp.h:281) ==20091== by 0x715BAC: js::mjit::Recompiler::recompile() (Retcon.cpp:269) ==20091== by 0x4E4069: js::types::TypeCompartment::processPendingRecompiles(JSContext*) (jsinfer.cpp:1938) ==20091== by 0x414415: js::types::TypeCompartment::checkPendingRecompiles(JSContext*) (jsinferinlines.h:185) ==20091== by 0x4EDB95: JSScript::typeSetThis(JSContext*, long) (jsinferinlines.h:590) ==20091== by 0x4E3A40: js::types::TypeCompartment::dynamicCall(JSContext*, JSObject*, js::CallArgs const&, bool) (jsinfer.cpp:1793) ==20091== by 0x4FC697: JSContext::typeMonitorCall(js::CallArgs const&, bool) (jsinferinlines.h:414) ==20091== by 0x711A66: js::mjit::stubs::CompileFunction(js::VMFrame&, unsigned int) (InvokeHelpers.cpp:309) ==20091== by 0x41B0213: ??? ==20091== by 0x68E0DB: js::mjit::EnterMethodJIT(JSContext*, JSStackFrame*, void*, js::Value*) (MethodJIT.cpp:744) ==20091== Address 0x3fc333330000005c is not stack'd, malloc'd or (recently) free'd ==20091== ==20091== ==20091== Process terminating with default action of signal 11 (SIGSEGV)

When monitoring argument types at calls to stubs::CompileFunction, we did not wait for the newly pushed frame to be sufficiently initialized. http://hg.mozilla.org/projects/jaegermonkey/rev/695726698bfe
