Is this bug still valid? I haven't seen these failures on ToT (r164860) on Mavericks with 32 bit build. (In reply to comment #2) > Is this bug still valid?

Can you post the 15 new ones here? At some point we should whip the 32-bit code into shape. :-/ Here's the complete list: ** The following JSC stress test failures have been introduced: stress/recurse-infinitely-on-getter.js.default stress/recurse-infinitely-on-getter.js.always-trigger-copy-phase stress/recurse-infinitely-on-getter.js.no-cjit-validate-phases stress/recurse-infinitely-on-getter.js.dfg-eager stress/recurse-infinitely-on-getter.js.dfg-eager-no-cjit-validate regress/script-tests/call-spread-call.js.default regress/script-tests/call-spread-call.js.no-llint regress/script-tests/call-spread-call.js.always-trigger-copy-phase regress/script-tests/call-spread-call.js.no-cjit-validate-phases regress/script-tests/call-spread-call.js.dfg-eager regress/script-tests/call-spread-call.js.dfg-eager-no-cjit-validate regress/script-tests/string-cons-tower.js.dfg-eager regress/script-tests/string-cons-tower.js.dfg-eager-no-cjit-validate jsc-layout-tests.yaml/js/script-tests/dfg-convert-this-dom-window.js.layout-no-llint jsc-layout-tests.yaml/js/script-tests/dfg-convert-this-dom-window.js.layout-dfg-eager-no-cjit jsc-layout-tests.yaml/js/script-tests/function-call-aliased.js.layout-no-llint jsc-layout-tests.yaml/js/script-tests/function-call-aliased.js.layout-dfg-eager-no-cjit Results for JSC stress tests: 17 failures found.

The 6 stress/equals-masquerader.js tests now passes with the fix for https://bugs.webkit.org/show_bug.cgi?id=129947. The 5 stress/recurse-infinitely-on-getter.js testa are still failing. With the fix for https://bugs.webkit.org/show_bug.cgi?id=129969, the stress/recurse-infinitely-on-getter.js tests no longer crashes. The jsc stress tests are passing completely for me on 32-bit. I haven't been able to reproduce Ossy's reentrant-caching.js failures. However, that test also exercises stack overflow errors. Hence, it is possible that Ossy saw that on his machine and not the stress/recurse-infinitely-on-getter.js because of difference in the compilers we use generating code with difference amount or stack usage, and also different OS'es with different stack sizes. I think it's reasonable to conclude at this point that the issue has been fixed with https://bugs.webkit.org/show_bug.cgi?id=129969. Ossy, I'll going this bug as resolved since I don't see anymore jsc stress test failures on x86 32-bit. If you the failures manifest still, feel free to file a new bug and assign it to me.
