The bug happens when exceptions that are raised with parameters by the runtime are caught by a try/finally
construct in the compiled code. The finally
block re-raises the exception through the runtime's exception_raise
, which clears the parameters. Fixing this properly needs making the compiler aware of exception parameters - not clearing the parameters when the compiled code raises an exception is not enough, e.g.
try: ... except SomeException: # This does need to clear the parameters # (and change the ID of the exception re-raised by finally) raise SomeOtherException finally: ...
This bug is manifesting itself all the time at the moment, as the whole kernel code is encapsulated in a try/finally
construct to handle RTIO handovers.

Please close when new-py2llvm is usable with the rest of ARTIQ.
