Andrea, thanks for including the gdb.txt file as it pointed to the problem. To fix the problem, at the first gdb prompt, keyin:
handle SIG32 pass nostop noprint
You might also want to keyin next:
set pa off
because then you do not have to keep typing "c" as a page fills up. Next just type in as Andrew said:
run (or simply r)
What GG does is he keeps a .gdbinit file in his home directory so that he does not have to type in the handle and set lines over and over again as he does a lot of debugging. The file, .gdbinit, is a hidden file so starts with the "." and the one he uses is attached here.
