- Subject: find command with gdb v7.0
Hi,
I wanted to try out the new find command wivh gdb v7.0. I used the
example given in this page
(http://sourceware.org/gdb/current/onlinedocs/gdb_11.html#SEC91). I just
added one line (line no 5) to the example given. It looks like the
search doesn't start at given location.
In the attached output, you can see that the find command says it
couldn't find the first word or part of it, but is able to find the
second word. Is it a bug, or am I doing something wrong?
(gdb) find greet,+100,"greetings"
Pattern not found.
(gdb) find greet,+100,"ings"
Pattern not found.
Thanks,
James Pandavan
