2020-06-23openjp2: Error out if failing to create Tier 1 handle.Sebastian Rasmussen
Previously when the handle failed to be created (e.g. when opj_calloc returned NULL due to low memory), the code still assumed that the t1 handle pointer was valid and dereferenced NULL, causing a crash. After this commit OpenJPEG will instead error out under this condition. This fixes issue #1255.
