Hello,

Currently working on the upgrade for the pkgsrc port of webkitgtk from 1.10.2 to 2.0.4..

We're experiencing lately problems with both 1.10.2 and the work in progress during the build of the WebKit-1.0.gir target.

WebKit was configured with the following options:

An extract of the output is (BTW we've patched the WebKit: missing ':' at column type of problems):

  GEN    WebKit-1.0.gir

I notice that Source/WTF/wtf/FastMalloc.cpp is not current with the latest gproftool's TCMalloc
(notably for TCMalloc_PageHeap::GrowHeap).

Currently I'm testing a build with --enable-fast-malloc=no, but would it be possible to update these bits
to the latest TCMalloc code (https://code.google.com/p/gperftools/) which is the recently released 2.1?
