Package: clang-13
Version: 1:13.0.0-5
Severity: normal
Dear Maintainer,
-static -fsanitize=undefined causes unusable a.out as below:
$ clang-13 -static -fsanitize=undefined hello.c
$ ./a.out
Segmentation fault
On the other hand, gcc-11 produces a usable a.out:
$ gcc-11 -static -fsanitize=undefined hello.c
$ ./a.out
hello world!
Best regards, Ryutaroh Matsumoto
