Has anyone else seen this issue?
I am working off svn- the crash is always in the same spot,
in the decoder, in nb_celp, in both filter_mem2
(if st->lpc_enh_enabled == 1) and iir_mem2 (if == 0)
The function in question is filter_mem2_10 or
_mm_loadu_ps is an unaligned load and all of the
data seems to be ok, and no sigill- get a sigsegv.
Same code works fine on windoze. CPU in question
is a 2.8 ghz hyperthread- xmm/SSE supported. C
versions of same functions solve the issue- same
problem with multiple 3.3, 3.4 gcc versions.
