</tt><tt>the "test case" I referred to requires the compilation of
our whole back-end. It segdaults when using gcc-4.4.3 under
Ubuntu 10.04, with other combinations I have tested it still
happens (before your patch) but is not noticeable unless using
gdb. I have tried making valgrind catch it but no success... so
I guess the only way to *see* it is using the debugger.</tt><tt><br>

Hexagon as well but now I seem unable to reproduce it :S</tt><tt><br>
