I used gdb several times (successfully), but each time that I try it on the Korn-shell and give the shell a pipelined command (with a few built-in commands, e.g. print 'qwertyui' | cat - ) and I place a break at c_print (even without this break, if I recall correctly), I get a core-dump from gdb and it never stops at the breakpoint. Where can I find documentation on gdb so I can check on restraints in its use? I hope the GNU people take a look at this and fix it if there is something wrong. Please respond to me directly because it's hard to go through the bulk-mail that I get from this group. _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
