In the testsuite for C++ is the file g++.dg/ext/utf16-4.C
I just tried to compile this file with the GNU C++ compiler
version 4.4 snapshot 20090109 using valgrind.
The debug output was
g++.dg/ext/utf16-4.C:6:29: error: empty character constant
==9851== Conditional jump or move depends on uninitialised value(s)
==9851== at 0x5807A8: c_lex_with_flags (c-lex.c:992)

==9851== by 0x4D1C22: c_parse_file (parser.c:304)
==9851== by 0x58840C: c_common_parse_file (c-opts.c:1243)

==9851== by 0x5CF1585: (below main) (in /lib64/libc-2.9.so)
It might be a good idea to process this broken C++ code
in a cleaner way.
