Source horribly out-of-sync

I am a relatively new user of GCC and GDB, though I¹ve used many, many other
compilers and debuggers over the years ­ including some very low-level ones.
I¹ve run into a problem, which is likely caused by my build (I suppose),
that I¹ve not yet been able to figure out: When I debug a static-library
I¹ve built using GDB, the source lines ­ including the referenced files ­
are horribly out of sync. For example, I will *known* that I¹m in, say,
A.CPP, but GDB reports me being at some odd line in B.CPP.

The static library is built using pretty normal, as far as I can tell, GCC
options: -ggdb3 ­O0 ­Wall ­frepo. The library is designed as part of an
Apache module I¹m writing, but I¹ve seen the same effect when
linking/debugging it within a small test harness. The code is relatively
clean ISO C++. It does have a few inline functions (mostly quick checks) and
uses a couple of templates (the auto_ptr and basic_string from the STL and a
modified form of auto_ptr I use for items not allocated through new). Other
than that, it¹s straightforward code. It does link in the Apache Portable
Runtime and LibXML2/XSLT, but I (more or less) treat those as black-boxes.

I¹m building on Mac OS X 10.3 (the latest Panther build) using the GCC and
GDB provided by Apple (GCC 3.3 and GDB 5.3).

I welcome any thoughts and suggestions. I do not subscribe to this list and
so would appreciate being cc¹d on any responses.

Thank you,
Brendan
