The crash is at the end of the function during stack check, so presumably the bug happened earlier. Maybe asan can help.

Does not reproduce with llvmorg-18.1.8 (3b5b5c1ec4a3095ab096dd780e84d7ab81f3d7ff) build from source

avikivity commented 2 months ago

Although, maybe clang itself wasn't build with stack smashing protection.

avikivity commented 2 months ago

Did not reproduce with llvmorg-18.1.6, so likely need extra fortification.

avikivity commented 2 months ago

Plain llvmorg-18.1.6 with -fstack-protector-all did not reproduce.

@fpasserby looks like your commit f78688134026686288a8d310b493d9327753a022 fixed cs-pgo; can it be backported to 18.1?

avikivity commented 1 month ago

Looks like it's not intended as a fix but rather feature; so it fixed cs-pgo incidentally.

[coro][pgo] Do not insert counters in the `suspend` block (#71262)

If we did, we couldn't lower symmetric transfer resumes to tail calls.

We can instrument the other 2 edges instead, as long as they also don't
point to the same basic block.

@mtrofin any ideas how to fix this for 18.1.6?

@mtrofin can you help here? clang 18.1 is broken with coroutines + pgo.
