Hi @Johan, Thanks for the tips.

With export ASAN_OPTIONS=detect_stack_use_after_return=1,  I get 
this results for 
https://github.com/ldc-developers/ldc/blob/master/tests/sanitizers/asan_fiber.d.


On my Mecca style fiber, all my own unittest passed on macOS, but 
on linux I get wired error at random:

https://gist.github.com/InnotSagg/9217ebd4d9b50e9b77ae8ae24b6cc51b

The error line is on function declaration, only get with linux + 
nolto + norelease.

I am not sure it related with 
https://github.com/dlang/dmd/pull/12012,  this error stop my work 
for days and I have no clue.
