[jira] Commented: (HARMONY-4407) [DRLVM][stack]One page on the stack is not enough to create SOE on Windows x86-64.

    [ https://issues.apache.org/jira/browse/HARMONY-4407?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12515685 ] 

Pavel Afremov commented on HARMONY-4407:
----------------------------------------

Patch fixes JET works. Under debugger OPT works OK too. Without debugging in stress condition VM in OPT mode can return code 128 - crashes without any printing.
