The docuementation get_browser function and script causes segmentation fault. I saw the earlier reports on this, but as I'm not using 4.04 I figured this bug had been squashed. If the fix is still only available in CVS then I'm sorry for this.

Which browscap.ini are you using?

[2001-01-08 14:08 UTC] lsimon at

The latest from the Browserhawk site. 

my user agent as variable is Mozilla/4.72 [en] (X11; I; Linux 2.2.17 i586; Nav)

I see nothing like browscap.ini on browsehawk site. Can you
give a pointer?

[2001-01-08 14:44 UTC] lsimon at

http://www.browserhawk.com/browscap/

This is the site recommended in the FAQ for obtaining a browscap.ini

Incidentally, I cannot find my browser in the browscap.ini file I have. But supposing someone's browser is not in that file, I suspect that we still don't want php to segfault. Is there a better place to find a browscap.ini that you know of? You'd think that Mozilla/4.72 would be in the list I have, but alas.

There are some bugs there indeed, I'm working on it.

[2001-01-08 15:15 UTC] stas@php.net

Please try current CVS - it should work now. If not, please
reopen.
