Created attachment 11712
  --> https://sourceware.org/bugzilla/attachment.cgi?id=11712&action=edit
test case

The attached test case, when compiled and run shows a symbol which isn't
demangled by addr2line. I'll attach the file, and the compiled file

_GLOBAL__sub_I__Z11print_tracev

The output below shows it as item [2].

It is the same as running manually addr2line

$ addr2line -f -C -e exception4 0x0000000000001600
_GLOBAL__sub_I__Z11print_tracev
