I cannot get the "smaller reproducer" to fail (with trunk); but your minimal testcase in comment 1 fails alright (needs no compiler options at all): 81317-2.c:4:21: internal compiler error: Segmentation fault ( 1, jsimd_ycc_extbgrx_convert_altivec_outptr ) ^ 0x102e1ad4 tree_class_check(tree_node*, tree_code_class, char const*, int, char const*) /home/segher/src/gcc/gcc/tree.h:3205 0x102e1ad4 altivec_resolve_overloaded_builtin(unsigned int, tree_node*, void*) /home/segher/src/gcc/gcc/config/rs6000/rs6000-c.c:6458 (The first arg to tree_class_check is NULL). So, confirmed.
