[PHP-DEV] 3.0.6 Sporadic ODBC Failures From: Michael Brennen (mbrennen <email protected>)
Date: 12/28/98

I've checked out 3.0.6 as well as the very latest CVS tree of about a
half hour ago (late Sunday evening in US Central time zone) and I'm
still getting sporadic (frequent, actually) failures with the unified
ODBC driver against Solid. I hope the backtrace below is useful.
This was compiled with -g -O, so hopefully the line number references
are accurate.

Rasmus, I know I worked on this a couple of weeks ago but I was
getting very inconsistent and meaningless results trying to compile
with -g or -g -O. I don't know if it matters, but on the machine I was
on before I had installed egcs; the machine I'm working on now is Suse
Linux running gcc 2.7.2.1 (for some reason they don't have 2.7.2.3).
It seems to be giving much more coherent results.

Anyway, this is on a test machine so I can install test versions on it
as needed to find this. Thanks,
