[erlang-bugs] gcc bug triggered by compiling R14B02 (not an erlang bug per se)

I glanced at Debian's patches, but they're 200k lines long. Did not
feel like digging through that to try and understand what they've
done. Feels like "report and forget" time.
Anything more than the rest of this mail I should send to Debian?
gcc -v: gcc version 4.5.2 (Debian 4.5.2-11)
uname -a: Linux contorpis.corelatus.se 2.6.38-2-amd64 #1 SMP Thu Apr 7 04:28:07 UTC 2011 x86_64 GNU/Linux
how to reproduce:
gcc -O3 -c preprocessed.i
here's what it looks like on my machine:
> gcc -O3 -c preprocessed.i
beam/dist.c: In function ‘erts_do_net_exits’:
beam/dist.c:501:1: internal compiler error: in dfs_enumerate_from, at cfganal.c:1207
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.5/README.Bugs> for instructions.

Problem does not occur with "gcc version 4.4.5 (Debian 4.4.5-15)"
