Crash report when attempt to run other app

Targets macOS
1

This tries to run an external application called “dosbox” (an unix executable with exactly this name, no app package, found at Daum Cafe).
Other DOSBox ports started from within the application developed with XOJO runs fine (the framework is Cocoa based).
The Shell command stored in app.ausfuehren (text string) is compiled by code, providing the path to the 3rd-party application and options to be sent to.
It will be executed from within a superclass “Thread” named as “Class1”, which contains these lines, among other lines:

app.s=new Shell app.s.Mode=2 ... // app.s.Execute app.ausfuehren

The method app.rundosbox calls the lines above by using:

t = new Class1 t.run

Properties affected are:
ausfuehren as string
PathToDaum as string: “/Applications/20140127_Intel_i386/dosbox” (as provided by the 3rd-party developer)
t as thread
s as shell, all of them added as property to the superclass “app”.

While other DOSBox ports will be executed without problems, this one crashes all the time.
So far I’ve determined, this port doesn’t like quotation marks in its options line (will not execute at all, if set with),

Without the XOJO-developed application, when I run the external application in request from within the Terminal.app, it runs fine.
So I think, it doesn’t like to be executed from within other applications, except someone of you could find what’s going wrong, please.

Try this

dim f as folderitem
f=specialfolder.applications.child("20140127_Intel_i386").child("dosbox.exe")
if f<>nil then 
    if f.exists then f.launch
end if

no shell required.

Thanks for the reply, I’ll look into this.

Would mean I need to write customer’s settings into the default configurations file (name and location) of this external application.

Development continued, now replacing the configuration file of the second application with user’s settings.

Terminal output is as follow:

Any ideas about “Bus error: 10”?
It happens when I press a key, when the other application is active.
