SIGILL in layout tests on Mac |
||||||||||||||||||||||
Issue descriptionThe following test is failing on various Mac: https://test-results.appspot.com/dashboards/flakiness_dashboard.html#testType=webkit_tests&showExpectations=true&tests=custom-properties%2Fregister-property-syntax-parsing.html crash log for renderer (pid <unknown>): STDOUT: #CRASHED - renderer STDERR: Received signal 4 <unknown> 00010fdd628c STDERR: [0x00010de627ec] STDERR: [0x00010de626e1] STDERR: [0x7fffeaaa6bba] STDERR: [0x000000000000] STDERR: [0x00010fb2aa36] STDERR: [0x00010d3d3271] STDERR: [0x00010d4545dc] STDERR: [0x00010d453b9d] STDERR: [0x2f625b10437d] STDERR: [end of stack trace] Signal 4 is SIGILL (see https://developer.apple.com/legacy/library/documentation/Darwin/Reference/ManPages/man3/signal.3.html) The regression range contains following clang roll: https://chromium.googlesource.com/chromium/src/+/4d3a24b0257cb96368b91fb006893c69d296e121 Seems like the new clang miscompile something here.

The regression range is: https://chromium.googlesource.com/chromium/src/+log/11e15a648963d343125c2bb95369f4bfa178ea69%5E..d9fd37f3280a4e6373b359b8fabf3ec7fc4dff2f?pretty=fuller Clang roll is the only suspicious change in this range.

(SIGILL may mean assertion failure, but I assume some diagnosis is printed on stdout or stderr in that case.)
