Windows crashes with netmgr-based statschannel
16-Jul-2020 21:34:32.694 c:\builds\isc-projects\bind9\lib\isc\buffer.c:76: REQUIRE((((b) != ((void *)0)) && (((const isc__magic_t *)(b))->magic == (0x42756621U)))) failed
I have not seen such crashes before,
a pipeline ran for d8e6b32a did not trigger these crashes,
the only code-related MR merged between the last successful pipeline and the first crashing one was !3847 (merged),
there is a fair chance that !3847 (merged) introduced a Windows-specific bug (or a generic one that is simply easier to trigger on Windows).
