The following event occurs very frequently :
Breakpoint 2, work_ipc_layer (FDS=0x11ffff188) at ipc_layer.c:224
224             if ( ( gwa.no_clients < gwa.max_clients ) &&
(gdb) n
225                  ( gwa.listener_state == LISTENER_CONNECTED ) )
(gdb) n
224             if ( ( gwa.no_clients < gwa.max_clients ) &&
(gdb) n

(gdb) n
warning: Hit heuristic-fence-post without finding
warning: enclosing function for address 0x3ff8019ca20
This warning occurs if you are debugging a function without any symbols
(for example, in a stripped executable).  In that case, you may wish to
increase the size of the search with the `set heuristic-fence-post' command.

Otherwise, you told GDB there was a function where there isn't one, or
(more likely) you have encountered a bug in GDB.

283             if ( gwa.listener_state == LISTENER_CONNECTED )
(gdb)                

This despite the fact that the program has been compiled with the -g flag to gcc.

Please help!


>How-To-Repeat:
I do not know how this can be done in the general case. But I have a really big program and I set the breakpoint at main and from there on I continue single stepping / continuing, addding / removing break points. Suddenly this message pops up
