The test case is test/recover.go in the master Go sources. But I know that that test won't work on other architectures, because currently reflect.MakeFunc is only implemented for 386 and amd64. It should be possible to implement reflect.MakeFunc for all architectures in a somewhat inefficient manner by using libffi's closure API. I have not tried that. It is also of course possible to implement support for any specific processor as I did for 386 and amd64. The difficulty depends on the difficulty of the ABI. In general it's not too hard but it requires a clear understanding of ABI details and assembly language programming with full backtrace information. It's about 600 lines of code for amd64. Ian
