Description hdu@apache.org 2013-11-29 14:34:53 UTC

The "User-defined Literals" (aka. "Extensible Literals") suggested in http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2378.pdf made it into the C++11 standard.

So compilers supporting this can run into an undecidable parsing ambiguity when there is a string concatenation where the concatenation parts are not properly separated. These situations must be resolved to prevent compilation aborts.
