Description

Created attachment 520521 [details]
shell testcase, unpack, chdir and run main.js with options "-n -m -a"

The attached testcase either crashes or asserts on TI tip (tested on 64 bit). The original testcase crashed in [JSC::X86Assembler::cmpl_im], the reduce testcase here asserts instead. The test itself is fragile, minimization was only possible while keeping the lengths of all filenames involved.
Recompilations could be triggered by obj->lookupProperty (e.g. by resolve hooks creating prototype objects for scripted functions), which the IC code did not anticipate and needs to watch for.
