Me (powerpc) has the same problem. The problem is that in rred.cc:258 an
incomplete object dyn is created, due to _error->PendingError() in
contrib/mmap.cc:223 returns true. The object has the attribute Base=0
which is feed to mmap in contrib/mmap.cc:270 on object destruction. This
call causes the segfault.
I don't know if Base == 0 is a valid state for a DynamicMMap object and
the destructor has to check this value or if there's something else
rotten and Base == 0 signals a deeper broken state.
More stuff after further research:
Executing _GetErrorObj()->DumpErrors() yields this message:
E: Couldn't make mmap of 2393964544 bytes - mmap (12: Cannot allocate memory)
The last 4 bytes of the patch are 0x8eb10000 == 2393964544:
