After commit "local scope for types of function parameters" debugging
does not work any more.
If I compile:
#include <stdio.h>
int main(void)
{
printf("Hello World\n");
return 0;
}
And start gdb and try to set break on main I get:
invalid dwarf2 offset 0xffffffff
If I revert the tccdbg.c change (See attachment) debugging works again.
