I have cleaned up some areas, but now cost_index() is getting that problem with temp as NaN because it has exceeded it's range or something strange like that. Does psql \do work on stock 6.5? Here is the weird part. This is with no optimization, and of course the assert at the end fails on the test temp >= 0.

With assert checking enabled, does \do crash psql in 6.5? -- Bruce Momjian | http://www.op.net/~candle maillist@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026

Works for me, with sources from about 30 June. Someone's broken
something since then, perhaps.

The call to ceil() in plancat.c did not have a prototype, so it thought ceil() returned an int, so it caused an invalid float value that was only caught later on in cost_index(). -- Bruce Momjian | http://www.op.net/~candle maillist@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026

It was a call to ceil() without a prototype, causing invalid float value that was only caught later. Not sure why it was not showing up earlier. -- Bruce Momjian | http://www.op.net/~candle maillist@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026
