Hi List,

Firstly, apologies to the list maintainer, I originally sent this email
from the wrong address [email protected].

I'm trying to eliminate the errors from my program. As noted in the
documentation, I'm looking at the first error listed.

A look at the error shows that it's happening in a function called
readCommand, which is called by getCommands() and processLines().
valgrind shows that processLines() contains a call to getCommands in
kyodoc.cpp line 319. That's right. It seems to suggest that
getCommands() contains a call to readCommand in new_allocator.h, line
62, but that seems to be wrong - in fact, getCommands() contains a call
to readCommand() in kyodoc.cpp line 106.

The problem I have here is that because valgrind doesn't seem to be
telling me which line the problem in readCommand is occuring, so I'm not
sure how to find this out.

Perhaps the code address, 0x80B8646 can help me. How to match that up to
a location in the program?

Thanks for any help, and best regards,

Seb James
