http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49852 --- Comment #6 from Jürg Billeter j at bitron dot ch 2011-07-26 15:43:11 UTC --- It works here now, both, just calling cxxfilt and the full ld command from libreoffice. Thanks for the quick fix. For some reason, 'make' didn't rebuild libbfd after updating cp-mangle.c. After 'make clean' it looks all fine, though.
