Had an assertion error for `delv` utility in trying to perform suspend
thread.
Doesn't seem specific to any thing, argument-wise.
Environment:
Linux 4.19
Debian 10.3
Custom built Bind v9.17.1
bind9/lib/isc/app.c:422
void
isc_app_ctxsuspend(isc_appctx_t *ctx) {
REQUIRE(VALID_APPCTX(ctx));
REQUIRE(atomic_load(&ctx->running));
/*
* Don't send the reload signal if we're shutting down.
*/
if (atomic_load_acquire(&ctx->shutdown_requested) == false) {
Traceback:
# delv -v
delv 9.17.1-dev
Gdb reported:
