Internal error.

Hi there,
I got two bugs for you. In the first case, an error message would be
sufficient (if the construct is not legal, but I can't image it is). In
the second case
the compiler simply does not work, it takes about 1GB virtual memory and
does not generate an object :-(
Please contact me, if there any questions,
best regards,
Stephan Jacobi
