I just tried to compile the Suse Linux package spandsp-0.0.3-43 with the GNU C compiler version 4.3 snapshot 20071102
The compiler said v17rx.c: In function 'v17_rx_restart': v17rx.c:12020: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. Source code attached. Flags -O2 -ftree-vectorize -w -std=gnu99 required.
