Sucks to get ix slaves for your Valgrind run: https://tbpl.mozilla.org/?showall=1&tree=Mozilla-Inbound&rev=8a36e37f46ed got a run on bld-linux64-ix-030 which failed this way, and a retrigger on bld-linux64-ix-036 which failed the same way; the push before it had been green on bld-centos6-hp-013 and my retrigger there on bld-centos6-hp-015 was green, so I backed out 8a36e37f46ed, and my backout was green on bld-centos6-hp-013. After five green pushes on various centos-hp and ec2 slaves, bld-linux64-ix-036 had a red run, which I attributed to the backout having required a clobber, despite the extreme unlikeliness of that. Four pushes later, https://tbpl.mozilla.org/php/getParsedLog.php?id=34396034&tree=Mozilla-Inbound, bld-linux64-ix-035 has the same failure, despite not having done an inbound Valgrind run since January 27th, and despite clobbering. No idea how this can be the case, but this particular Valgrind failure is bld-linux64-ix-*-only.

Passing a garbage string to unlink(), perhaps?

Reproduced locally, by accident when looking for something else. Looks like someone somewhere is doing unlink(NULL). Syscall param unlink(pathname) points to unaddressable byte(s) at 0x349F0E60C7: unlink (syscall-template.S:82) by 0x7A10033: ffi_call_unix64 (in /home/sewardj/MOZ/MC-12-02-2014/ff-opt-linux64/toolkit/library/libxul.so) by 0x7A0F989: ffi_call (ffi64.c:485) by 0x768AC35: js::ctypes::FunctionType::Call(JSContext*, unsigned int, JS::Value*) (CTypes.cpp:5854) by 0x797E76B: js::Invoke(JSContext*, JS::CallArgs, js::MaybeConstruct) (jscntxtinlines.h:230) by 0x789E2FA: js_fun_apply(JSContext*, unsigned int, JS::Value*) (jsfun.cpp:1069) by 0x797E5D9: js::Invoke(JSContext*, JS::CallArgs, js::MaybeConstruct) (jscntxtinlines.h:230) by 0x797A595: Interpret(JSContext*, js::RunState&) (Interpreter.cpp:2608) by 0x797DDA1: js::RunScript(JSContext*, js::RunState&) (Interpreter.cpp:423) by 0x797E538: js::Invoke(JSContext*, JS::CallArgs, js::MaybeConstruct) (Interpreter.cpp:495) by 0x789E2FA: js_fun_apply(JSContext*, unsigned int, JS::Value*) (jsfun.cpp:1069) by 0x797E5D9: js::Invoke(JSContext*, JS::CallArgs, js::MaybeConstruct) (jscntxtinlines.h:230) Address 0x0 is not stack'd, malloc'd or (recently) free'd

Well, yes :) I had a quick look at the code in the stack, and it's extremely generic call-a-function code -- the function and its argument are both arguments passed down from above. If you can catch it in a debugger and do some inspection to see which JS function is involved, that would be helpful.
