/tmp/ccDX2LCa.s: Assembler messages:
/tmp/ccDX2LCa.s:152: Error: symbol `this_symbol_is_defined_once_or_twice' is
already defined
This does not happen on a ia32 platform. The bug above was distilled from CLN.
It is responsible for the package failing to build on Debian/sid
<http://buildd.debian.org/fetch.php?&pkg=cln&ver=1.1.9-4&arch=ia64&stamp=1123630039&file=log&as=raw>.
It appears to happen on m68k, too:
<http://buildd.debian.org/fetch.php?&pkg=cln&ver=1.1.9-4&arch=m68k&stamp=1123757682&file=log&as=raw>.
