Package: clang-3.2
Version: 1:3.2repack-11
Severity: normal
Dear Maintainer,
I seems some file is missing to enable the functionality required by the
"-fsanitize=undefined" option. Maybe it should be included in some
suggested or recomended package?
A simple shell session showing the problem follows:
$ cat test.c
int main (int argc, char **argv) { }
$ clang test.c
$ clang -fsanitize=undefined test.c
/usr/bin/ld: impossibile trovare
/usr/bin/../lib/clang/3.2/lib/linux/libclang_rt.ubsan-x86_64.a: File o
directory non esistente
clang: error: linker command failed with exit code 1 (use -v to see
invocation)
