Clang crash reproducer
We hit this assertion error recently when using -fprofile-instr-generate, the
original source file this was triggered by is
https://fuchsia.googlesource.com/fuchsia/+/8e92e01f1ec5d1314b1fd7fbaf7de5e9d60f1282/zircon/system/ulib/async-loop/loop.c,
reproducer is attached.
clang:
/src/clang-llvm/llvm-project/clang/lib/CodeGen/CoverageMappingGen.cpp:692: void
(anonymous namespace)::CounterCoverageMappingBuilder::popRegions(size_t):
Assertion `SpellingRegion(SM, Region).isInSourceOrder()' failed.
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash
backtrace, preprocessed source, and associated run script.
