Tor segfaults on OpenBSD/sparc64 on startup. GDB backtrace: #0 siphash24 (src=0xfffffffffffcdc34, src_sz=20, key=Variable "key" is not avai lable. ) at src/ext/csiphash.c:118 118 memcpy(&mi, in, 8); (gdb) bt #0 siphash24 (src=0xfffffffffffcdc34, src_sz=20, key=Variable "key" is not avai lable. ) at src/ext/csiphash.c:118 #1 0x00000026f1b853c8 in node_get_mutable_by_id (identity_digest=Variable "iden tity_digest" is not available. ) As you can easily see, node_get_mutable_by_id passes an unaligned pointer to siphash24, which memcpy then tries to copy from. This is a (struct node_t)->identity, so maybe that struct should have alignment padding? **Trac**: **Username**: pstumpf
