[jira] Commented: (HARMONY-5893) [drlvm][signal] stack trace is not available for failing asserts

["Ilya Berezhniuk (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HARMONY-5893?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12619721#action_12619721 ] 

Ilya Berezhniuk commented on HARMONY-5893:
------------------------------------------

I reproduced the problem on Win'x64.

Unfortunately, when I looked through CRT sources, I found that register context is prepared manually by CRT just before program termination.
I see no way to catch ABORT with register context - although CRT emulates 'signal' function and allows catching SIGABRT, it does not provide 'sigaction' which receives registers.

So the only solution I can see is preparing register context manually right in SIGABRT handler,  like CRT does.
I'll try this way and report results.

> There is quite annoying peculiarity of crash handler, it reports no stack trace in case of failed assert "due to missing register info".
> Would be really nice to fix this.
