Bad mangled name in shared library

[Jon Griffiths]

Hi,

I am having trouble with a very large shared library in C++. The
library compiles and links fine, however I cannot use my debugger on
programs linked to it due to apparent errors in the stabs (I compile
with -g -gstabs+).

I'm using:
GNU ld version 2.14.90.0.7 20031029
GNU objdump 2.14.90.0.7 20031029

However the problem manifests with ld/objdump 2.13.90.0.18 as well.
I'm running GNU/Linux Mandrake 10 community.

objdump -g on the compiled .so gives:

/usr/local/lib/libagingvisual.dll.so:     file format elf32-i386

Googling for the error doesn't give any real clues. Does anyone have
any idea if this is a binutils or gcc bug, and how I can go about
working around it?
