I just downloaded the PostgreSQL client tools and noticed that psql

fine.

What can I do - if anything at all - to debug the issue? Obviously, I
cannot test every single snapshot after October last year and see where
the crash "starts"...

It isn't clear why you couldn't do that

There were at around twenty five snapshots since October. To test them all would take a long time...

...but surprisingly already the first post 1.7.17 snapshot from 2012-11-
23 exhibits the problem[1].

but you could at least provide
*details* like cygcheck output

see attached file


and what you mean by "crash".

From a DOS prompt:


psql --version
1 [main] psql 3196 exception::handle: Exception: STATUS_ACCESS_VIOLATION
626 [main] psql 3196 open_stackdumpfile: Dumping stack trace to
psql.exe.stackdump

And from a bash prompt:

$ psql --version
Segmentation fault

If there is a stackdump file then posting that would be useful.

confirmed, I see the same.


strangely I noticed that psql of 9.2.2-1 does not suffer this problem,
and it seems due to cygpq.dll (rebase address ?).
I will investigate later
