Good point. Let me try to refresh the memory about it and get back to that.

This is might be misleading. If you built gst with the generational Garbage Collector then the SIGSEGV is a "barrier" and to be expected. Paolo came up with the idea of using "mprotect" to make pages unwritable and then handling SIGSEGV to know that a write (to an object in the eden) was made.

Your error might be a different. In GDB one can type something like "handle sigsegv ignore" and the program will continue to run until it hits the real error.

Oh? I have used it many years in production system.
