Honestly, I haven't the foggiest. I didn't see anything dodgy in the DLL
list you posted earlier or any of the other info you've provided.
To progress, I think you'd need to get a usable backtrace to show how
and where the crash happens. Use Visual Studio (or the free Express
Edition) or use windbg from Debugging Tools for Windows. Set the symbol
path appropriately. Use the debugger to run pg_dump with appropriate
arguments, and when it crashes, get a backtrace (stack trace) of the
There's some guidance on debugging on Windows here:
It's written for getting a stack trace of a BACKEND, and you want to get
a stack trace of the CLIENT (pg_dump) so it's not quite the same, but
you'll require the same tools and the same initial configuration of the
symbol path etc. Instead of attaching to a running postgres.exe though
you must run a new pg_dump via the debugger.
