-Subject: [PATCH] Fix stack overflow with specially crafted files
-
-The file is not malformed per se, it just has a huge XRefStm chain
-and we end up exhausting the stack space trying to parse them all.
-
-Having more than 4096 XRefStm seems like won't really happen on real
-life so break the flow at that point
-
-Fixes #936
