A way back in 2015 I pointed this error before here:
http://apache-http-server.18135.x6.nabble.com/2-4-17-dev-crash-libapr-1-dll-tt5024061.html#none
Quote from Yann there:
Answer from a Apache-dev: puzzled about how node->next (ie.

(AFAICT)... The other pointers don't seem to be corrupted.
Still the error is there, maybe you can help to find the cause.
