Hi

Since updating libpng and php 5.2 (to use the new php52 port), code that
has previously worked find using gs, now causes an Apache abort, this is
what appears in the log:

[Wed Apr 28 14:42:30 2010] [notice] child pid 3064 exit signal Abort
trap (6)

The code itself uses tcpdf (www.tcpdf.org) to create a pdf form which in
turn uses two png images. If these images are commented out, or even
changed to jpeg (though this is not ideal as they have transparency) we
get the above problem.

Before updating php-gd (but after libpng), we had the "png_check_sig"
but the patch had been applied.

This is on:
FreeBSD smb.ksm.pri 8.0-RELEASE-p2 FreeBSD 8.0-RELEASE-p2 #0: Tue Jan 5
21:11:58 UTC 2010
root(a)amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC amd64

Apache version is 2.2.14

Anybody know what's going on with this, and if it's fixable??

Thanks
Daren

Oops... Sorry I meant to say we *don't* get that problem!! It's only
when it is a png image that we get the abort.

I had something similar a while back, and ended up downgrading libpng
with portdowngrade (to 1.2.38 ), is probably worth a try.

I was thinking about that, but wouldn't I then have to downgrade
dependencies? I was hoping to avoid that as I like a clean(ish) system!
