Are you talking about sequences like this?
int_fast16_t sample_buffer[ring_size][w+6], *sample[ring_size];
memset(sample_buffer, 0, sizeof(sample_buffer));
BTW, gcc 4.3.0 on x86_64 fails the same way as 4.4-svn on the Snow
regression tests. Not sure how much that matters in the grand scheme
given Snow's current status, but it is certainly cause for suspicion
that earlier gcc versions are okay with it.
4.3.0 on PPC fails exactly the same as the other PPC configs, as expected.
I wonder if I could automatically log the error output of a 'make test'
run for db logging by combining grep and tail somehow?
