Miscompilation appears when I've added "-fpeel-loops" but probably all CFLAGS beside "-O2" are treated as unsafe?;) Yeah, I am unsure about adding it to filter-flags will deserve the effort (as there are another ton of cflags that could break it too :/) It looks on SPARC udns doesn't work correctly even with -O2. Should be fixed in 0.4. |
