<pre>LLVM12 and later (tested main branch at
2c5c06c5cfca7988b2d69a78459be27beb35a86f) produces broken binaries on FreeBSD
13 for powerpc64 and powerpc64le. The binaries will crash with segmentation.
Steps to reproduce using FreeBSD 13 RELEASE ISO:
1. Install llvm12 (apt install llvm12)
2. Create echo_crash.c:
#include <capsicum_helpers.h>
#include <err.h>
int
main(int argc, char *argv[])
{
if (caph_limit_stdio() < 0 || caph_enter() < 0)
err(1, "capsicum");
return 0;
}
3. Compile with:
clang12 -O2 -g echo_crash.c -o echo_crash.good
clang12 -O2 -g -fstack-protector-strong echo_crash.c -o echo_crash.bad
4. Execute the binaries produced.
./echo_crash.good: will produce no output and return normally.
./echo_crash.bad: Segmentation Fault</pre>
