Thanks for the replies so far. Unfortunately is the best option (set
variables in bash) not feasable.
The .bat file is a complex set of bat files with logic inside so that
would take a lot of effort to convert
But I have done some experiments with bash without --login option and
the advised export

The problem can be reproduced with cygwin1-20050916.dll
The output of strace in the case of a stackdump is below.

No problem. here is a new trace (similar to the original) and the related
stackdump

Yes sure. You can see this in the header of the dump its says:
DLL version: 1005.19, api: 0.138
DLL build:20050916 00:00:39SNP
In order to be sure that we are talking about the same things:
I have all these variables in DOS and start bash from a CMD window with command

OK, I stand corrected.

Perhaps I do not understand it. I was talking about invoking cygin from
native.
The native environment grows far over 32 k. It just does not show up in
bash.
If I can help by testing the new snapshot: please supply some hints.

I have done three tests:
below the maximum
exactly the maximum
over the maximum

Here are the results of the test below the maximum

Further empirical tests turned out that the environment in Windows NT
is not limited
Thanks for the answer.
