m-holger f0343565ed Tighten checks for invalid indirect references during xref reconstruction 2024-01-17 14:11:57 +00:00
m-holger 6e3b7982db Fix incorrect handling of invalid negative object ids 
Fix two errors introduced in #1110 and #1112. Since
#1110, encountering the invalid indirect reference #1110
-2147483648 n R produces an integer underflow which, if
 undetected, immediately trigger a logic error. Since
 #1112, object -1 0 R may be incorrectly identified as
 an earlier generation of itself and deleted,
 invalidating a live iterator.
