I can't reproduce this with DMD-1.017 on Linux. Maybe it is "rebuild" only bug?

Added to DStress as

Sorry, the example is wrong. This should fire the error:

auto bla = "\U80000000";
src/Parser.d(125): invalid UTF character \U80000000
rebuild: root.c:1490: void OutBuffer::writeUTF8(unsigned int): Assertion `0'
failed.

Created an attachment (id=350)
 --> (http://d.puremagic.com/issues/attachment.cgi?id=350&action=view)
Patch against DMD2.029

This is a trivial one. After printing the error message, just change it to a
valid char to avoid the later ICE.

The Unicode codespace is 0 to 10FFFF, which is a 21 bit space.  So \U80000000
is not a valid Unicode codepoint.

Even for ISO 10646, which is a 31 bit space (and has an interesting
relationship to Unicode), \U80000000 is not a valid ISO 10646 codepoint either.

I'd expect \U80000000 to be a "gigo bug".  Still, should not cause ICE.
