I must correct myself, haveged segfaults on _all_ Debian Sid machines I

have access to, the backtrace is virtually the same every time.

Thanks for tracking this down.

Here is a better backtrace.

Next interesting find: If I recompile using -O0 (i.e. without any optimization), haveged works fine.

And again, using -O1 results in the following (different) backtrace.

Maybe not a eglibc bug, but a bug inside haveged, which is know to be compiler dependant for its "magic".

Yes, using gcc-4.3 instead of gcc-4.4 "resolves" this bug.
