Following program
program test;{$IFDEF UNIX}uses cthreads;{$ENDIF}begin     writeln('test');end. Compile with FPC 3.0.4 on FreeBSD 12. When run test program, it causes segmentation fault.  What is wrong? Without cthreads unit, it run fine.

Possibly a linker issue. See if you can change the linker to ld.bfd

Hello.

When compiling your code with fpc installed from freebsd package:

$ sudo pkg install fpc
$ sudo pkg install lang/fpc-units

All is OK, your test.pas run as expected.

But compiling your code with fpc compiled from source, there is indeed that error message:
fish: "./test" terminated by signal SIGSEGV 5Address boundary error)

@fredvs yes I install from source code.

Hum, so, imho, the MakeFile provided by official FPC download source has something wrong.
I did try to using fpmake to re-create it but the resulted MakeFile did not fix the problem.

Maybe the creator of the fpc FreeBSD package could give some light what to change in the MakeFile.

I used this script:

!/bin/sh
COMPILER=/usr/local/lib/fpc/3.0.4/ppcx64
gmake clean
gmake all FPC=$COMPILER OPT="-Fl/usr/local/lib"
gmake FPC=$COMPILER install INSTALL_PREFIX=/usr/local/

This compiles and install fpc 3.0.4 but, like explained, your application compiles ok but crash while running.

A contrario the compiler installed via the official pkg of FreeBSD gives a compiled program that runs ok:

$ sudo pkg update
$ sudo pkg install fpc
$ sudo pkg install lang/fpc-units
