Hi,
When i step into:
(*func) (program, argv);
gdb exits.
func is execv, and program is "/usr/local/libexec/gcc/avr/3.4.3/cc1"
How do i get into cc1 so i can set breakpoints there?

Run it by hand - gcc -v will show you the command line. GDB has very
limited support for debugging across exec, depending on your platform.

Hi,
Cc1 runs ok at the command line:
/usr/local/libexec/gcc/avr/3.4.3/cc1 -quiet -v main.c -quiet -dumpbase main.c -dP -mmcu=atmega16
-auxbase main -g -O0 -Wall -Wno-unused -version -o /tmp/cccVrfqY.s
When i try to run the same thing in gdb, it crashes:
Program received signal SIGSEGV, Segmentation fault.
0x080f3cd1 in init_emit () at ../../gcc-3.4.3/gcc/emit-rtl.c:5354
/home/russell/SRC/gcc-3.4.3/gcc/emit-rtl.c:5354:138102:beg:0x80f3cd1
(gdb)
It crashes in emit-rtl.c here:
/* Indicate that the virtual registers and stack locations are
all pointers. */
REG_POINTER (stack_pointer_rtx) = 1;
