            Bug ID: 179479
           Summary: [JSC][MIPS] Sampling Profiler crashes with functions
                    of arity >=6
           Product: WebKit
           Version: Other
          Hardware: Other
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: guijemont at igalia.com

Quite a few tests tend to crash with the sampling profiler turned on, and after looking at them a bit, I came up with the following minimal test case that crashes about every second time on MIPS when run with jsc --useSamplingProfiler=true:

function bar(a,b,c,d,e,f) {
}

noInline(bar);

for (var i = 0; i < 10000; ++i)
    bar();
