This was a "typo" in the code. The comment explained the + correct behavior, and the code was clearly intended to handle this + issue, but the implementation had an error in it. This is fixed by + a single-line change, which can be found in git commit + 4bc434000c42a7191e705c8a38216ca6743ad9ff. That commit can be used + as a patch that applies cleanly against qpdf 8.1.0 and forward. + The bug was introduced in version 8.1.0. For the record, this is + the first bug in qpdf's history that could result in silent loss + of data when processing a correct input file. Fixes #276. + 2019-01-12 Jay Berkenbilt <ejb@ql.org> * In the --pages option, allow the same page to be specified more |
