From 3533605293e8083dae19c5fbd41e2077faf5adc6 Mon Sep 17 00:00:00 2001 From: Zebediah Figura Date: Mon, 29 Jun 2020 15:12:22 -0500 Subject: [PATCH] msvcrt: Print assertion failure messages to stderr. This matches Windows behaviour. In particular, redirecting stderr with freopen() followed by assert(0) will print the failure message to the relevant file.
