No crash here:
$> tcc crash.c
crash.c:12: ',' expected

Ok the error message doesn't really make sense. This is because within
parse_function_parameters() tcc trys to detect whether it parses an old
style K&R function definition or a modern prototype. This is done by
evaluating the return value of parse_btype() from the first parameter,
if no type is found then tcc assumes it deals with a K&R style function.

This is the case with your example, if you change it to the following:

void foo(int a /* correct 1st parameter */, invalid_type b){}

You get an appropriate error: invalid type. I don't have a solution right now.

Regards,
Marc
