[fpc-pascal] Segmentation fault with cthreads on FreeBSD
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) -- Sent from: http://free-pascal-general.1045716.n5.nabble.com/ ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

@fredvs yes I install from source code. Zamrony P.

> @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 -- Sent from: http://free-pascal-general.1045716.n5.nabble.com/ ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
