So, I'm working on this libsass CMOD glue (a totally new world for me) and have a question:
From the CMOD a callback in the Pike layer is called. If the Pike layer callback throws an error, how do I detect that in the CMOD? As it is now the error is thrown in the Pike layer and the backtrace is output to the console, but the C code after the callback still continues.
How do I prevent this?

You need to do this:
JMP_BUF recovery; if (SETJMP(recovery)) { /* Something was thrown, value in throw_value */ UNSETJMP(recovery); /* If you're not going to rethrow, you need to free */ free_svalue(&throw_value); mark_free_svalue (&throw_value); } else { /* Do stuff that can throw */
UNSETJMP(recovery); }

Thanks a bunch. Worked like a charm :)
