[poppler] [Poppler]A bug in poppler-private.cc?

[cobra.yu]

Dears,

    No "globalParams=0;" after line 238 of poppler-private.cc could be a bug? In my application, I use a loop to load PDF files with some hex-string errors separately. The latter files with errors would confront a "globalParams" that should have been deleted, but kept the old value. And in such case, line 1579 of GlobalParams.cc: "return errQuiet;" would raise an Access Violation Exception. Maybe the addition of "globalParams=0;" after line 238 of poppler-private.cc would be a better way.
    Any one has also experienced this?
