Now a got some more information:

(gdb) p s->Sseg
$2 = -32768

You can see that p s->Sseg is negative.
Either I made an error when I recompiled dmd or there is another place where
short has to be changed to int.
Just like in changeset 456 my line in cc.h is:
#if TX86

    int Sseg;            // segment index


The complete output:

Program received signal SIGSEGV, Segmentation fault.
