C++: ICE 61

[Martin v. Loewis]

> ../../include/Widget/GapBuffer.hh:52: Internal compiler error 61.

Thanks for your bug report. I've simplified your test case a bit, and
include a patch below.

Please note that the application is in error, use -pedantic to see
why. However, the compiler should not crash; with the change below,
it is rejected properly.

Regards,
Martin
