#2 tclMuPdf segmentation fault

[Franco Violi]

In version 2.1.0 the attached PDF, generated by RICOH scanners, generates a segmentation fault in the close method. In attachement you find also a program duplicating the problem.

The version we tested was 2.1.1. I apologize.

Hi Franco,
I was able to reproduce the BUG. I have a development release in progress and it still crashes on that pdf.
That pdf is corrupted, the core-mupdf issues a warning (see below), and I suppose the problem is there (i.e. core-mupdf does not properly deallocates the memory ...)
Have you tried to open/close that pdf with the original mupdf tools ?
Next week I will try to debug ..

• A even more simple crash-test is the following:

package require tclMuPDF
mupdf::printwarnings true ;# --- enable warnings
set pdfObj [mupdf::open PROBLEM.pdf]
# --> MuPDF Warning:: broken xref subsection, proceeding anyway.
$pdfObj close ;# --> crash

BUG FIXED.
See the new release 2.2

Hi Aldo. We will test the new deployment ASAP. Thanks a lot. Ciao. Franco.
