[mythtv-users] Help with gdb

[Stephen Robertson]

I'm trying to use gdb to get some more information on a problem I am
seeing but I am having problems.
Using the suggested gdbcommands file contents then I get a problem
when starting.  CPU shoots up to 100% and I get this in gdb.txt

Function "qFatal" not defined.
Breakpoint 1 (qFatal) pending.
[Thread debugging using libthread_db enabled]
warning: (Internal error: pc 0xb5da079b in read in psymtab, but not in symtab.)
... followed by lots of lines similar to the last one.


The contents of gdbcommands is:
handle SIGPIPE nostop noprint
handle SIG33 nostop noprint
set logging on
set pagination off
set breakpoint pending on
break qFatal
set args -l mythfrontend.log
run
thread apply all bt full
set logging off

If I take break qFatal out then mythfrontend starts up ok but I
presume I am losing some useful information?  For reference the
problem I am having is: http://svn.mythtv.org/trac/ticket/6956

Thanks
Stephen
