Subject: importpage results in endless recursion (cross-reference-related?)
Download (untitled) / with headers
text/plain 1.2k
The attached single-page PDF (which seems to be correct, as far as I can tell) results in an endless recursion when calling import_page with PDF::API2 version 2.028. With version 2.025 I get the message that cross-reference files are not supported, so the issue might be cross-reference-related. I attached a minimal script to reproduce the issue (it's basically just calling import_page). The stack trace might show the cause of the issue: ... PDF::API2::Basic::PDF::File::read_objnum(ref(PDF::API2::Basic::PDF::File), undef, 0) PDF::API2::Basic::PDF::File::read_objnum(ref(PDF::API2::Basic::PDF::File), undef, 0) PDF::API2::Basic::PDF::File::read_objnum(ref(PDF::API2::Basic::PDF::File), undef, undef) PDF::API2::Basic::PDF::File::read_obj(ref(PDF::API2::Basic::PDF::File), ref(PDF::API2::Basic::PDF::Array)) PDF::API2::Basic::PDF::Objind::realise(ref(PDF::API2::Basic::PDF::Array)) PDF::API2::importPageIntoForm(ref(PDF::API2), ref(PDF::API2), ref(PDF::API2::Page)) PDF::API2::import_page(ref(PDF::API2), ref(PDF::API2), 1) Note that read_obj calls read_objnum with an undefined $num, which results in the endless recursion. I guess at least read_objnum should return if called this way, so the endless recursion would not occur. Whether further things need to be fixed is beyond my insight... Thanks for checking..!

This is due to the same bug as RT #113293, which was just patched. The fix will be in the next release (2.029).

Yep, I can confirm that this bugfix solves my problem - now that is a nasty language "feature"! Thanks a lot!
