php52-gd causing apache abort

[Daren Russell]

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 at 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
