Handling Segfaults

What is the most portable way to catch segfaults together with their addresses and then resuming at the place where it happened? I.e. to handle array out of bounds exception by expanding array.

I know it is done with signal() on POSIX and with SetUnhandledExceptionFilter() on Windows. But you cant define signal() for Windows, because it has its own stripped down version, useful only for the purpose of handling CTRL-C.

Both don't signal() and SetUnhandledExceptionFilter() have no means of recovering from error.

Ok. I've decided to throw in my own libc, calling directly into kernel32.
