AW: [PHP-DEV] PHP 4.0 Bug #8744 Updated: call to header() causes CGI error From: Harald Radi (h.radi <email protected>)
Date: 01/17/01

hi,

a few comments to this, my (afaik already closed) and the #8571 bug reports:

in fact the provided information about this bug is insufficient, but it's
definitly a bug.
since the error appears in irregular intervals with the same script it's
hard to find any
dependencies. i will try to find the shortest script that generates this
error.

a few hints:
when i use a https connection the error occours more often.
i don't get the error when i work local (on the webserver), but i get it
when i access the same machine remote.

it would be helpful if i could tell php to be more verbose. (i.e. log
internal function calls to see where the execution stops)

if someone could tell me how to debug php on a win32 platform i would give
my best to localize this bug.

harald.

> Our situation is similar to that in bug report 8571, particularly
