Description Andrew Pinski 2005-02-28 01:32:50 UTC 
The following "invalid" (well valid if we say that VLA is a GCC extension) ICE in fold_convert:
template<typename T> void foo(T t)
{
  int f[t];
}

Also we don't reject this with -pedantic in 2.95.3-3.4.0 either so that is not a regression.

There might be missing a processing_template somewhere.
Comment 1 Andrew Pinski 2005-02-28 01:36:40 UTC 
Note this worked with 3.5.0 20040909.
Comment 2 Andrew Pinski 2005-02-28 01:49:01 UTC 
And it fails with 20050113.  Those are the two closest compilers I have.
Comment 3 Wolfgang Bangerth 2005-02-28 15:35:41 UTC 
This seems to work with the latest version I have, which is from 20050130. 
I don't know what's going on...

Comment 4 Wolfgang Bangerth 2005-02-28 15:37:57 UTC 
It also seems to be working with a snapshot from yesterday that I had on 
another machine. Andrew, can you double-check with something newer?

Comment 5 Andrew Pinski 2005-02-28 15:47:43 UTC 
It passes with 20041124.

Oh, it does pass with 20050225 so closing as fixed then.
