There's an unaligned word access in ninja's murmurhash implementation:
https://github.com/martine/ninja/blob/master/src/hash_map.h
We need to change
unsigned int k = *(unsigned int *)data;
to
unsigned int k;
memcpy(&k, data, sizeof k);
and it should fix the unaligned accesses on strict arches like sparc64 and mips.
Sorry, I'm not able to fix this myself right now, but I can help
upstream the fix tomorrow. (I'm of course ok with any ports fix for
this.)
