I think the changes for this issue are causing the crash and unexpected buffer expansion described in Issue 23985. Appending to a bytearray() can overstep the memory buffer because it doesn’t account for ob_start when checking for resizing. And “del” can expand the allocated memory due to an off-by-one error. Please have a look at my patches. Perhaps there are other operations that also need patching to account for ob_start.
