Comment #10 on issue 884 by [email protected]: shell sample Infinite
loop in JSObject::LookupCallbackSetterInPrototypes
http://code.google.com/p/v8/issues/detail?id=884
I reduced part of V8 sources into the test case where GCC 4.5.1 removes a
store to the field when compiling file with -O1 -fstrict-aliasing.
I opened an issue in GCC bugtracker for this testcase:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45883
I am still not sure whether this is a strict aliasing violation or a bug in
GCC alias analysis.
I will wait for GCC developers response and then update this issue.
