Comment(by igloo):
Looks like this problem is caused by ar replacing object files in
libraries, which happens when xargs adds them in different ar invocations:
{{{
$ AR="c:/Program Files/Haskell Platform/2009.2.0.2/bin/ar"
$ rm z.a
$ "$AR" clqs z.a Data/ByteString/Char8_o_split/Char8__11.o
Data/ByteString/Lazy/Char8_o_split/Char8__11.o
$ ls -l z.a
-rwxr-xr-x 1 ian None 3548 2010-03-23 20:01 z.a
$ nm z.a | grep
bytestringzm0zi9zi1zi5_DataziByteStringziChar8_readFile1_closure
00000014 D
_bytestringzm0zi9zi1zi5_DataziByteStringziChar8_readFile1_closure
$ rm z.a
$ "$AR" clqs z.a Data/ByteString/Char8_o_split/Char8__11.o
$ "$AR" clqs z.a Data/ByteString/Lazy/Char8_o_split/Char8__11.o
$ ls -l z.a
-rwxr-xr-x 1 ian None 678 2010-03-23 20:01 z.a
$ nm z.a | grep
bytestringzm0zi9zi1zi5_DataziByteStringziChar8_readFile1_closure
}}}
The same thing happens with all these ar's:
