 New Comment:

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

A reproduction script using GD directly would be extremely helpful, along with 
the configure lines used both in PHP 5.4.14 and 5.4.15 and any difference in 
libpng versions, please.

Description:
------------
I am using PEAR Image_Canvas to dynamically generate some images. The same 
script 
has worked from PHP 4.x all the way through to 5.4.14. Basically the script 
layers 
several transparent png files together to make a combined image

I just upgraded to 5.4.15 and the images are no longing rendering properly. 
Certain elements are replaced by solid rectangles and others have a variety of 
color changes. It seems like it might be a transparency issue with PNG files, 
but 
not sure.

Reverting to 5.4.14 instantly fixes the images.
