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 iir_mem2_10 _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. Thanks!
