This leaves me wondering: Is this really architecture-dependent, or is it just due to chance (different addresses, hash collisions, etc.) that it works for me and not for you?
I guess you're on x86? My machines are amd64
My questions for you are: 1. What version of libc6-dev do you have installed?
ii gcc 4:4.7.2-1 amd64 GNU C compiler ii gdb 7.4.1-3 amd64 The GNU Debugger ii libc6-dev:amd6 2.13-38 amd64 Embedded GNU C Library: Developme
2. What do you get for "info variables optind"?
Not at all the same as you: (gdb) info variables optind All variables matching regular expression "optind": Non-debugging symbols: 0x0000000000600930 optind@@GLIBC_2.2.5 Interesting - "non-debugging symbols"? Maybe I should install libc6-dbg? Well, with libc6-dbg I get different output from info variables: All variables matching regular expression "optind": File getopt.c: int optind; Non-debugging symbols: 0x0000000000600930 optind@@GLIBC_2.2.5 But "p" still doesn't show the version I want: (gdb) p &optind $1 = (int *) 0x7ffff7dd7130
