thanks
I tried to debug this by adding printf statements and came to the
conclusion that it appears to be a compiler bug. It crashed during a
call to a callback. Adding printf statements to that callback stopped it
crashing (but it went on to crash in another similar callback)
Givent this suspicion I tried disabling optimisation. This was a little
tricky as though there was a CFLAGS set in debian/rules it didn't seem
to have any affect on the build process. However that did not fix it.
I established that the last time a buildd successfully built this on arm
it used gcc-4.1 and afaict the buildds never tried to build it with 4.2.
So the next thing I tried was using older gcc versions 4.2 failed and
4.1 works
A patch to make afnix build using g++-4.1 on arm has been attatched.
Note: my testing was done in qemu, I don't have access to real arm hardware.
