           Summary: r134080 causes heap problem on linux systems where
                    PAGESIZE != 4096
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: kilvadyb at homejinni.com

On linux systems where PAGESIZE == 16k we could use webkit/jsc with USE_SYSTEM_MALLOC=1 until r134080 caused memory handling problems like FastMalloc. With modifying 2 constant values it can be fixed. Still a question if static const size_t s_regionSize = 64 * KB; in class Region; of BlockAllocator.h should also be modified ( a higher value would be more efficient for bigger PAGESIZE?).
