<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> </head> <body> Hello, Referring to my previous patch :<a class="moz-txt-link-freetext" href="https://lists.cairographics.org/archives/cairo/2020-August/029019.html">https://lists.cairographics.org/archives/cairo/2020-August/029019.html</a> <div class="moz-cite-prefix">I have replaced this with other patch on my local computes (see the attachment). Basically, I have removed function _cairo_image_surface_is_size_valid() and all code related to it. The reason? pixman library makes such tests every time. Let them decide what is valid and what not.

Subtle example: The patch from that mail multiplies two ints and then casts the result to uint64_t. Any integer overflows would already happen before the cast.
