20:13 <agentzh> fche: just committed a quick fix for my register patch to master: https://www.sourceware.org/git/?p=systemtap.git;a=commit;h=39caf3f3fd0d7ced7193f10b6407017c95e24ff0

20:14 <agentzh> otherwise reading 64-bit x86_64 registers would be broken in master.

20:14 <agentzh> also added some new tests to cover this case.

20:15 <agentzh> sorry about that.

20:16 <agentzh> i noted this regression when running our own ylang test suite with the latest stap.

20:50 <agentzh> it's worth mentioning that to locate the issue in our test case, i took advantage of our stap patch which adds stap backtrace printing support for runtime exceptions (error(), assert(), and etc).

20:50 <agentzh> this was the backtrace which clearly shows the location: https://pastebin.com/YpFQuTAg

20:51 <agentzh> otherwise it would took me much longer to pinpoint it.

20:51 <agentzh> *would take me

20:52 <agentzh> we'll propose the stap bt printing patch to the mailing list for review soon.
