Subject: Does the Cygwin setup program do internal sanity checks on startup?
Date: Wed, 24 Aug 2022 20:46:10 +0000	[thread overview]
Message-ID: <> (raw)

Why would I ask that question? Because I have a host running a hodgepodge of company-mandated security software, and -- only on that host -- the Cygwin setup tool crashes...

1. The crash generates 3 dump files when I use procdump, which is odd since I "normally" only get 2 identical dumps from procdump.
2. A Websense ForcePoint DLP DLL is loaded in the process space, apparently through DLL injection.
3. There seem to be 3 threads started, only one of which is the setup program's "main" function. I had to get that out of a Process Monitor log since the dump files are largely content free.
4. The crash is unique to the setup program. Nothing else appears to fail.

The crash is an "illegal instruction" dump, which of course doesn't make a lot of sense... This could be one of the other security packages/policies on this host being "helpful."

I need ammunition to take to my internal Mordak's so I can update Cygwin... Sure I can use WSL, but not for everything.
