Comment #1 on issue 1924 by [email protected]: Parse error with
labelled statements
http://code.google.com/p/v8/issues/detail?id=1924
Thanks for the report. We have a buggy optimization in the parser.
Here's the story: for a labeled 'if', we treat the arms as if they were
labeled. The test cases become internally:
if (0) a: break a;
if (0) b: { break b; } else b: { }
if (0) c: break c; else c: { }
And we have an optimization that kicks in where we replace "x: break x"
with an empty statement. This optimization has a bug, it does not consume
any following semicolon:
if (0) { } ;
if (0) b: { break b; } else b: { }
if (0) { } ; else c: { }
Anyone want to take a stab at fixing this?
