            Bug ID: 113891
           Summary: On FreeBSD, a statically linked program which runs a
                    std::thread aborts
           Product: gcc
           Version: 13.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org

g++13 -v

A simple program which launches a std::thread and is statically linked on
FreeBSD aborts. This is not an issue with dynamically linked program. This is
also not an issue with LLVM.

The gdb backtrace points to the function thread_start in FreeBSD's libthr
(thr_create.c). So I thought this would be an issue with the pthread
implementation but I sadly can't reproduce this with a C program.

The program was compiled with g++13 -pthread -static main.cc

I suspect this is due to the use of weak for pthread functions.

Most likely you need to force include all of libthr archive file.

I'm not sure how to get this done.
I tried it with -Wl,--no-as-needed, which aborts as well and
-Wl,--whole-archive but that does not compile with undefined reference errors
