           Summary: test/pdf2png.c:63: Mismatching allocation and
                    deallocation: absolute
           Product: cairo
           Version: 1.9.1
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: general
        AssignedTo: cworth at cworth.org
        ReportedBy: dvice_null at yahoo.com
         QAContact: cairo-bugs at cairographics.org

In latest git version. 

In file test/pdf2png.c:63: 
Variable absolute is allocated with:
absolute = g_strdup (filename);

And later released with:
free (absolute);

You should use g_free() (could not found documentation, but there is this bug
report where it is said so).

I don't normally report bugs in test files, but I made an exception as result
of this bug could be undefined behavior, which is not good in testing either.
