Description Andrew Niefer CLA 2005-06-17 14:50:48 EDT 
void isTrue( int field, int bit ){
   return ( (field) & (bit) );
}

The (field) & (bit) is being parsed as a cast expression instead of as a binary
expression.

This was found in the DOTL project (http://sourceforge.net/projects/dotl/) where
it takes the form of a macro 
#define IS_SET(flag,bit)  ((flag) & (bit))

This is an ambiguity. 
If field was a type rather than an parm passed in, it could even be valid.
Comment 2 Doug Schaefer CLA 2007-08-21 10:59:49 EDT 
Future means you commit to fix it in the Future. Inboxes can't make committments. Moving to '--'.

Created testcase AST2Tests.testBug100641_106279_castAmbiguity().
Fixed with bug 168924.
