Hi all,
We have a build system setup where we run our unit tests nightly with guard malloc and other stress testing environment variables and also have code coverage turned on. On 10.7 and 10.8 this is working well. On 10.9 it works too, but we get sporadic crashes like below. Has anyone else seen this? It looks like some edge case is causing the clang-inserted gcda file creation code to die.
Exception Type: EXC_BAD_ACCESS (SIGSEGV)
Exception Codes: KERN_INVALID_ADDRESS at 0xffffffffffffffff
