September 02, 2012 trying setjmp or throwing from signal handler crashes on OSX | ||||
---|---|---|---|---|
| ||||
Is there any way to get setjmp to work in a D program on OSX? I just get a segfault whenever it is called. I'm just trying to recover from a signal handler. Related questions: why is signal handler nothrow? I saw this related thread but it seems linux only: http://www.deadalnix.me/2012/03/24/get-an-exception-from-a-segfault-on-linux-x86-and-x86_64-using-some-black-magic/ with code: http://www.deadalnix.me/wp-content/uploads/2012/03/sigsegv.d.txt |

Both are Posix but at this low level the differences between the platforms start to show up. BTW, I get "Error: undefined identifier ucontext_t" when compiling that file on Mac OS X. -- /Jacob Carlborg |

I got that too. So I also tried linking my D program against a C library that would call those set jmp and long jmp functions, but that crashed too. So I guess there's currently no clean way to recover from signals on OSX ?
