auto foo = '\U80000000'; // invalid UTF character \U80000000 rebuild: root.c:1490: void OutBuffer::writeUTF8(unsigned int): Assertion `0' failed.

I can't reproduce this with DMD-1.017 on Linux. Maybe it is "rebuild" only bug? Added to DStress as http://dstress.kuehne.cn/compile/c/character_literal_02_A.d http://dstress.kuehne.cn/nocompile/c/character_literal_02_B.d http://dstress.kuehne.cn/nocompile/c/character_literal_02_C.d http://dstress.kuehne.cn/nocompile/c/character_literal_02_D.d http://dstress.kuehne.cn/nocompile/c/character_literal_02_E.d

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 attachment 350 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.

Fixed dmd 1.046 and 2.031

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.
