start_check_testcase does not involve debugger for client even if asked.

Comment by Oleksandr Byelkin [ 2019-12-25 ]

after rebuild for asan and back I can not reproduce anymore

Comment by Oleksandr Byelkin [ 2019-12-25 ]

No, I mixed up commits, in 10.5 still crashes, asan does not help

appeared problem in system PCRE2 (last ubuntu)

Comment by Ian Gilfillan [ 2020-02-10 ]

This is listed as fixed in 10.5.1, but there are no commits, and it's closed as Wont Fix. What is the correct status for this issue?

Comment by Sergei Golubchik [ 2020-02-10 ]

greenman, as far as I understand it was a PCRE2 bug, and updating PCRE2 in the VM fixed it.
