Bug ID: 48738
Summary: When running certain Batch files, my Wine cmd.exe
reproducible crashes with "page fault on read access"
or with "stack overflow in 32-bit code".
Product: Wine
Version: 5.3
Hardware: x86-64
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: cmd

Two batch files and the crashdump
I think the problem is new since middle of last year, at least reproducible
with Wine 5.2 and 5.3.
Find attached two small batch files: they should set some environment variables
and look for some directories, but they don't reach their end.
At real Windows (also when running at VirtualBox) they work properly instead.
Scenario:
create a directory and store one.bat and two.bat into it.
run: wineconsole one.bat
If the problem occurs, Wine crashes immediately.
("wine: Unhandled page fault on read access to FFFFFFF0 at address F7D2D3AB
(thread 01a8), starting debugger...")
The behavior depends very much on the content of the batch files:
adding commands or changing the variable's names may prevent it from crashing
or may shift the crash to a different line.
