| Subject: | png.c contains some invalid code |
in 0.49 png.c was updated to properly release the info_ptr block,
unfortunately this process incorrectly changed a function call.
On the compilers tested this just produces a warning, but it may produce
an error on others.
This code is never called, so as a work around that line can be deleted
or commented out.
In 0.50 the unreachable code (including the problematic function call)
will be removed.
