The CPU Jitter random number generator must not be compiled with optimizations.

Problem:

Build of the qdrant project version 1.17.1 fails:

Hello! Sorry about this build failure.

As a quick workaround, you can export AWS_LC_SYS_NO_JITTER_ENTROPY=1 in your environment to avoid this problem.

It looks like this is a FreeBSD ports build. We do have mitigations that strip optimization flags from CFLAGS before compiling jitterentropy, but something in your build environment is apparently getting past that. Could you share the values of CFLAGS and any target-specific variants (e.g., CFLAGS_x86_64_unknown_freebsd, TARGET_CFLAGS) that are set during the build? That would help us figure out what we're missing.

Thanks for the report!

AWS_LC_SYS_NO_JITTER_ENTROPY=1 works, thanks!

This is a FreeBSD port build.
