In IJG library's jmemmgr.c file we can define MEM_STATS to enable printing of memory trace logs when we have OOM. But if we enable it we get crash while disposing IJG stored objects in jmemmgr->free-pool() function.

This is happening because we delete the error handler before we actually start deleting IJG stored objects and while freeing the IJG objects we try to access cinfo->err->trace_level of error handler. This early deletion of error handler is happening in jpegloader.c->imageio_dispose() function. We should delete error handler after we are done with deleting IJG stored objects.
