../../gdb-7.2/gdb/breakpoint.c:7129: internal-error: expand_line_sal_maybe: Assertion `found' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.

I don't suppose you have a test case for this which I can use to reproduce it? Does it happen on any executable?

Solved

this error happen debugging a program that is build with libraries that have been built with a different/previous version of gcc. In my case, i rebuilt the libraries, re-built the main program and all works fine.

Issue can be closed as invalid.

Many thanks
