--- Comment #1 from Richard Smith <richard-llvm at metafoo.co.uk> 2012-06-15 00:11:02 CDT ---
Mostly fixed in r158487. We now only lex p[+-] as part of a pp-number if it's
preceded by 0[xX]([A-Za-z0-9]|[ep][+-])*. We could further reduce that to just
0[xX][A-Fa-f0-9]* if this is still an issue for anyone, but the immediate
problem with user-defined literals is now solved.
