Gcc usage questions should not be sent to the gcc list.  This list is 
for being doing development work on gcc.  This is an appropriate 
question for the gcc-help list.

It will probably do nothing unless you compiled with -pg.  The important 
bit here is that your program is apparently failing on the very first 
instruction it executes, as call_gmon_start is probably the first 
function in the init section, which contains initializers run before 
calling main.  So there is apparently something seriously wrong with 
your setup, e.g. the kernel isn't constructing the process stack 
correctly, or the process stack is being mapped to non-existent memory, 
or something else unusual is going wrong.  There may not be anything 
wrong with gcc itself.

call_gmon_start comes from glibc by the way.  Look there for more info.
