Reopen with a backtrace, please. http://www.gentoo.org/proj/en/qa/backtraces.xml

Would you mind trying wmupmon 0.1.3? Is is masked ~amd64 so you will have to ACCEPT_KEYWORDS="amd64" emerge wmupmon This version works fine here, if it works for you we just have to bug the amd64 arch maintainers...
Unfortunately i get the very same error with 0.1.3 ... Segmentation fault.
Silly question, but... do you have the /proc filesystem enabled in your kernel? What does it say when you cat /proc/uptime ?
zohar@gehirn:~$ cat /proc/uptime 220046.80 135990.87
OK. Re-assigning this to the amd64 arch team, as I haven't the hardware to reproduce your issue.
Starting program: /opt/wmupmon/src/wmupmon Program received signal SIGSEGV, Segmentation fault. main (argc=1, argv=0x7fff2df77108) at main.c:93 93 real_off_xpm[i] = backlight_off_xpm[i]; When debugging from directory containing sources (sorry, learning this).
Alright, this is fixed in 0.1.3-r1. The problem was that the code which calculated the size of an array didn't divide the sizeof(array) through the sizeof(array[0]) and then used that number of bytes to access the elements behind the array. All arches are affected by this, but as char* is twice as big on amd64 the chances are higher to hit the bug there.
r1 works for root, but still segfaults for a user...
Not here. I'm pretty sure this is another issue.. Can you provide the output of "strace wmupmon" please? You will have to merge dev-util/strace eventually.

(In reply to comment #11) > I'm pretty sure this is another issue.. Heh, that should have been "a different issue". I guess I shouldn't write comments at 1am ;) I can't see any reason why it would segfault (the strace output only shows libraries getting loaded), so I need a gdb backtrace as well: $ gdb wmupmon (gdb) run [it segfaults] (gdb) bt full [paste that stuff here] (gdb) quit Thanks

Sh** i forgot to remove the self compiled version with binding after emerging one, it was so long ago, omg you got me there. It works, i suck :/
