[SOLVED] Segmentation fault with 0.9

[moonman]

Hi

I have a problem with 0.9 on debian with PHP 5.2.0-8+etch1
I got Segmentation fault from weathermap but the same configuration is working on 0.82
I try it from the web and by running ./weathermap from cli
I will send you all the debug and configuration in private message

Thanks

I've reproduced this (I think) in Ubuntu Edgy Eft (based on Debian). I think it's now fixed. It's actually a one-liner - search Weathermap.class.php for the one occurence of ImageAlphaBlending, and remove the '#' comment marker from the front of that line. Why that stops php crashing, and why only on Debian, I have no idea.

I will probably try and get 0.9pre2 out today, as that's the last of the bugs I know about.

Or not. That introduces a rendering issue with some GD and truetype fonts now.

OK. It's a GD bug. It's documented here: http://bugs.libgd.org/4, and the reason it affects Debian is that Debian links to the system GD (version 2.0.33) not the built-in PHP one (2.0.28ish). For whatever reason, the problems aren't present in the PHP GD library, which has a different alpha-blending implementation as far as I can see from the docs.

My Windows and FreeBSD systems both use the built-in GD.

The bugs are apparently fixed in GD 2.0.34, which has been released and is in Debian unstable, if I understand Debian's release engineering website correctly.

In other words... SEP

Howie,

I upgrade to libgd2-xpm from unstable and now it work

Thanks for your help
