The guilty change is the following, which effectively turns on VM_LAZY_EXCEPTION support in exceptions_impl.cpp:

Heh, this regression is more interesting than it looked at first glance: JITs give the same output with identical stack trace, but test result is PASSED. By lucky chance I have older debug build at hand (svn = r474646) and it also spills this stacktrace to system err but status is PASSED for all execution engines. Looks like smth hase changed in exceptions processing for interpreter. 2006/11/15, Gregory Shimansky <[EMAIL PROTECTED]>: > Hello > > Today a kernel tests which used to pass a day ago started to fail.
