Test suite still fails, what to do?
Another common reason for failure to complete some particular test is simply bad code generated by a buggy component in toolchain or deficiency in run-time environment. There are few cases documented in PROBLEMS file, consult it for possible workaround before you beat the drum. Even if you don’t find solution or even mention there, do reserve for possibility of a compiler bug. Compiler bugs might appear in rather bizarre ways, they never make sense, and tend to emerge when you least expect them. In order to identify one, drop optimization level, e.g. by editing CFLAG line in top-level Makefile, recompile and re-run the test.
