That's a null pointer dereference. > As far as I can tell this is occurring inside BusyBox from libbb/xregcomp.c > in the "regcomp_or_errmsg()" function in the call to "regcomp()" itself. > > Any suggestions on what to look for would be appreciated. Thanks in > advance. You need to figure out what actual line is segfaulting. I'd stick dprintf(2,"here\n") calls into the busybox source to track down exactly where the segfault happens. (You can of course use gdb or some such, if you're feeling posh. :) If you can figure out what line is causing the segfault, and what the values of the variables used on that line are, it'd help a lot. Right now we don't know if it's a busybox problem or a uClibc problem. > PS. Before anyone asks, I'm not using "buildroot" Neither do I. :) Rob _______________________________________________ uClibc mailing list [email protected] http://busybox.net/cgi-bin/mailman/listinfo/uclibc
