+### Memory Leak Leading to VSCode Crashes
+
+There is a potential memory leak in the upstream shell integration that can cause VSCode to crash unexpectedly. When this occurs, VSCode and all related windows will close completely without warning.

+**Work-around:** there is no known workaround, but I do not hit this problem until gigabytes of terminal output, so it may not affect you.
