I just tried the above program and it worked perfect:
$cat - > test.pas
program ReproduceBug;
{$mode objfpc}{$H+}
uses
{$ifdef unix}cthreads;{$endif}
begin
writeln('using cthreads seems to be the root cause of this bug.');
end.

As you can see I have both gcc and libc installed for i386 and this programs
works.
i think this probably happens that the compiler finds the i386 linker and thus
looks for the i386 libs.
Can you please attach the link.res file?
