openjp2: Error out if failing to create Tier 1 handle.
 2020-06-22 21:03:23 +02:00
Sebastian Rasmussen 93b9f7236c openjp2: Error out if failing to create Tier 1 handle. 
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.
