I've had the same problem. It breaks the "set execution point" feature, which is a significant problem.

There is a bug in DDD when setting temporary breakpoints (which is also used by other commands, like set execution point). The answer received from GDB is something like

Breakpoint X at ADDRESS: file FILENAME, line LINE. << for breakpoints
Temporary breakpoint X at ADDRESS: file FILENAME, line LINE. << for tbreaks

In PosBuffer.C, there is a function which parses gdb answers and acquires information from it: gdb_filter. This function tries several cases, one of them is the UP and DOWN command outputs, with this if statement:

<code>
int at_index = answer.index(" at ");
int br_index = answer.index("Break");
if ( (at_index > 0) && (br_index < 0) )
</code>

As can be see, it looks for an "at" string at sentence not started by Break. But his comparison is bugged for temporary breakpoints, the correct code is:

<code>
int at_index = answer.index(" at ");
int br_index = answer.index("Break");
int tbr_index = answer.index("Temporary break");
if ( (at_index > 0) && (br_index < 0) && (tbr_index < 0) )
</code>

This will avoid many weird messages like: cannot find file /usr/src/0x12345 for example. Also it will avoid many unecessary info sources by ddd trying to find this weird file. If anyone wants a patch, let me know.
