            Bug ID: 261274
           Summary: leaking memory with cairo
           Product: WebKit
           Version: Other
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.

Calling `cairo_font_options_create()` returns a structure that contains an allocated property [0]. That used to be no problem when cairo font options were initialized just once, however this changed with commit 4fac13b14ab43258032797d51b868da33064af9e ("Network process shouldn't load Cairo ") [1] where the function is called when ever the data is used. Now the allocated property leaks, filling up all RAM over time.
