I'm still not seeing all of what I want to see because when you ran this test run the code generator gcc/testsuite/gcc/ms-sysv-generate.exe already existed and so was not rebuilt. I'm curious to know the full command line when it was built. Could you apply this patch and run it again? I should probably make sure that we rebuild the generator on each new run anyway. As far as the generator, it's not catching an exception that it should. I had been catching it by value because I always knew the type that was being thrown, but maybe there is some type of weirdness in your particular stdlibc++ implementation, so this patch also changes the catch to by-reference. Thanks, Daniel
