Bug#1101027: clang-19: clang -fsanitize=safe-stack causes link error

[Ryutaroh Matsumoto]

Package: clang-19
Version: 1:19.1.7-3
Severity: normal

Dear Maintainer,

The compiler option -fsanitize=safe-stack seems supported (or not?),
but we have the following linker error:

root at raspi4b-router2:~# cat hello.c
#include <stdio.h>
int main(void) { printf("hello\n"); return 0; }
root at raspi4b-router2:~# clang  -fsanitize=safe-stack  hello.c 
/bin/ld: cannot find /usr/lib/llvm-19/lib/clang/19/lib/aarch64-unknown-linux-gnu/libclang_rt.safestack.a: No such file or directory
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Best regards, Ryutaroh Matsumoto
