I am left wondering why the `validate` seems to be happy in Release and raises an error in Debug mode. I am investigating this issue at the moment, but I am happy to discuss possible issues, if anyone has an idea of what is going wrong. 1578211 1 pmatos 2019-10-09 06:31:12 -0700 Apologies - I meant since but 202569 : [JSC] Change signature of HostFunction to (JSGlobalObject*, CallFrame*) 1579299 2 ysuzuki 2019-10-11 16:33:34 -0700 This is non-CLoop 32bit issue (32bit JIT enabled JSC) and fixed in r250982. 1579638 3 pmatos 2019-10-14 08:38:22 -0700 (In reply to Yusuke Suzuki from comment #2) > This is non-CLoop 32bit issue (32bit JIT enabled JSC) and fixed in r250982.
