--- Begin Message ---Package: flex Version: 2.6.1-1.3 Severity: normal Hello Manoj, In flex 2.6 input() return 0 instead of EOF in the EOB_ACT_END_OF_FILE case: case EOB_ACT_END_OF_FILE: { - if ( yywrap( ) ) - return EOF; + if ( yywrap( ) ) + return 0; Since any user of input() needs to check its return value, this change breaks backward compatibility with pre-2.6 flex and is not documented anywhere I can see. Also what happens if the input stream includes NULs ? Cheers, -- Bill. <[email protected]> Imagine a large red swirl here.

--- Begin Message ---Hi, While it is true that the change was incompatible wwith what we had befire, the change was made almost four and a half years ago. I suspect we have gotten used to it now; and changing it back would just cause issues. I guess this is the new normal?
