15862 – [3.4/4.5 Regression] 'enum yn' fails (original) (raw)

Description Joseph Heled 2004-06-07 22:04:15 UTC

This short code snippet fails to compile. Worked in 3.3. As far as I can tell, yn is not a reserved word.

enum yn {Y, N}; enum yn x = Y;

Comment 1 Drea Pinski 2004-06-07 22:23:02 UTC

Confirmed, a regression.

Mark I feel that this is major parser bug which should be fixed for 3.4.1.

Comment 2 Wolfgang Bangerth 2004-06-07 22:33:10 UTC

No, yn is one of the Bessel function functions in C99 (do 'man yn'). The is a duplicate of another bug involving j1, which I'm going to look up next.

Comment 3 Drea Pinski 2004-06-07 22:38:46 UTC

That would be PR 14432 but since my 3.5.0 build was from last night this is not fixed.

Comment 4 Wolfgang Bangerth 2004-06-07 22:44:50 UTC

Right, I found PR 14432 as well. However, my 3.4 build compiles that one correctly, while it still fails on this PR. Mark, do you have an idea what is going on? This just seems too close to 14432 to be a coincidence...

Comment 5 Mark Mitchell 2004-06-09 16:33:30 UTC

Yes, we need to fix this for 3.4.1.

Comment 6 Mark Mitchell 2004-06-10 14:42:25 UTC

Working on a fix.

Comment 9 Mark Mitchell 2004-06-11 18:20:52 UTC

Fixed in GCC 3.4.1.
