DDD 3.2.98 fixes two minor bugs in DDD's parsing of breakpoint and
position information.  But these occurred under really unusual
circumstances (such as breakpoints at places w/o source, GDB breaking
lines of `info breakpoint' output, and likewise).  I hope these fixes
will help you out, although I'm pessimistic.

There's a `PosBuffer' class (in a file named `PosBuffer.C') which does
all the parsing of GDB's position information (notably, the method
`filter_gdb()').  

Although GDB is supposed to report the current location in a special
string using a `\032\032' prefix, GDB omits this information
sometimes, so DDD handles a wide variety of GDB messages.

Again, if you have a ~/.ddd/log file which reproduces the problem, it
would be easy to set up the `PosBuffer' class such that the specific
GDB message is parsed properly.

Best wishes,

Andreas
