Bug ID: 50161
Summary: Stack protector + coroutines + c++ exceptions causing
`musttail call must precede a ret with an optional
bitcast`
Product: libraries
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Common Code Generator Code
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
As the title said, we (Facebook) were hitting an assert with coroutines, stack
protector and c++ exceptions generating a musttail call that didn't immediately
precede a ret. I fixed it by cherrypicking the below:
5e3d9fcc3a8802cea5b850a3ca40c515d916bf82
I could run creduce and generate a simple example if need be, but the diff's
contents and it's description are pretty clear and the pick is clean.
