CreatePseudoConsole-crash-with-long-path

This repository automates reproducing CreatePseudoConsole crash when path to conpty.dll is long.

Usage

.\run-terminal-app.ps1 -DestinationDirLength <number>

The PowerShell command does the following:

1. Creates a new directory in the project root. The length of the directory full path is equal to the specified number.
2. Downloads Windows Terminal v1.19.10573.0 and extracts it to the created directory.
3. Runs the extracted WindowsTerminal.exe.

Steps to reproduce crashing CreatePseudoConsole

.\run-terminal-app.ps1 -DestinationDirLength 145

It runs for a few seconds and then terminates without showing the Windows Terminal UI. The generated output:

Generating destination directory of total full path length 145, base directory full path length: 47
Destination path: D:\CreatePseudoConsole-crash-with-long-path\tmp\aaaaaaaa\aaaaaaaa\aaaaaaaa\aaaaaaaa\aaaaaaaa\aaaaaaaa\aaaaaaaa\aaaaaaaa\aaaaaaaa\aaaaaaaa\aaaaaaa (length: 145, 11 new directories created)
