           Summary: setjmp is missing in DCTStream::init()
           Product: poppler
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: general

Created an attachment (id=41735)
 --> (https://bugs.freedesktop.org/attachment.cgi?id=41735)
patch to call setjmp before jpeg_create_decompress()

Kouhei Sutou noticed that DCTStream::init() does not setjmp before calling
jpeg_create_decompress(), which may call error_exit in exceptional cases and
cause longjmp with an uninitialized jmp_buf.

I may be paranoiac here, but anyway I'm attaching a patch.
