--- Comment #24 from Thiago Macieira <thiago at kde dot org> --- I'm seeing an infinite loop in NumericPattern::Scanner::scanForSigns with the same original testcase. Unfortunately, that's inlined in the NumericPattern constructor, so it's a little difficult to understand what's going on. I'll let the AI munch on this for a while.
