           Summary: mupdf generates a malloc(3) abord with this pdf
           Product: MuPDF
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P4
         Component: fitz
        AssignedTo: tor.andersson at artifex.com
        ReportedBy: cloos at jhcloos.com

When viewing the attached pdf with mupdf, glibc-2.9 (claims to) detect(s) a
memory corruption error during a call to malloc(3) and aborts.

Interestingly, running with MALLOC_CHECK_=1 or MALLOC_CHECK_=2 avoids the abort.

The malloc abort occurs in a call to fz_newname() with the string "PANTONE 7545
U".  I presume that is in 62 0 R.

It looks like something else, earlier, must set up the abort.

The only notable issue with the pdf is that it uses named spot colours and may
be, rather than a PDF generated by Illustrator, in Illustrator’s PDF-based save
format.
