This is the smallest example to reproduce the issue:

program ReproduceBug;

{$mode objfpc}{$H+}

uses
     {$ifdef unix}cthreads;{$endif}

begin
     writeln('using cthreads seems to be the root cause of this bug.');
end.


The code complies if the cthreads unit isn't included.

I played a bit with the installed packages, libc6-dev:i386 is the 
troublemaker. Probably some environmental variables are pointing to a 
wring directory.
