Bug description:
Binary package hint: binutils

$ echo 'int main(){}' > test.c
$ clang -g -c test.c
/tmp/cc-xPGs3W.s: Assembler messages:
/tmp/cc-xPGs3W.s:413: Fatal error: duplicate .debug_line sections
clang: error: assembler command failed with exit code 1 (use -v to see invocation)

http://llvm.org/bugs/show_bug.cgi?id=6218 says this is a binutils bug.  (“… there's nothing wrong with having multiple .debug_line section directives in a single .s file.  Compilers do this all the time.”)  This assembler message does not exist in upstream binutils or in Debian; it was added by the Ubuntu patch binutils/debian/patches/214-binutils-group.patch.
