stabs sections seem too large

I've noticed that with -g the stabs sections seem very large compared
to the text size. This is with the current snapshot, but also shows up
in 2.95.2.
e.g. for a simple C++ hello world application, I am seeing a .text of
632 bytes and a .stabstr of 144017 bytes.
An nm on the binary reveals only 59 symbols, so I can't really see
where the space is going.
Here's the command line output and the .ii file in bzip2 format:
