If you can reproduce this it would be helpful to run amuled in gdb and post a gdb backtrace.

I discovered just yesterday a bug in gcc 4.4 distributed with Ubuntu Karmic release... this but bug cause a stack corruption in crypto++ code. I'm trying to recompile everything using gcc 4.3 ...

Really a GCC problem? Or is that damned over-optimized lib?
With which GCC version is the lib compiled that ships with Karmic? It passes the cryptest.

I'm going really mad... problem is in crypto++... after submitting the bug to gcc stuff I got a reply and problems was not in gcc.. today (just some minutes ago) I got an assembly source, recompiled and got a wrong object code... so it seems that gcc produce correct assembly but GNU as fails. For some problems it compute badly jump offset. I don't understand why but code from ubuntu package works....

This was the problem http://sourceware.org/bugzilla/show_bug.cgi?id=10856... I updated ubuntu package and now it works correctly.
