Hi Dave,
> Do these two tests actually verify any particular behavior? Perhaps the
catch block could return 0 and the non-exceptional exit could return
non-zero, then the zero exit (that lit will check) demonstrates that the
exception occurred and was handled correctly?
The test throws unconditionally, so you either catch it correctly (and
return 0), or you fail to catch it and take down the JIT server with an
uncaught exception. In the latter case the JIT client reports a failure to
get the return value for main from the server.
I believe this answers your second questio: If you fail to register the EH
frames the exception will behave as if the catch block didn't exist, and
std::terminate will be called in the server.
- Lang.
