Closing DOS box leads to application error popup #66

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Cosmetic but irritating issue: run any of examples (ex. cefsimple.py) in MS-DOS 
command-line prompt (cmd.exe), switch from CEF window to DOS box, close it. A 
nasty application error "The instruction at ... referenced memory at ... The 
memory could not be read" popup arises.

How is it behaving when running the cefclient.exe sample browser from
the command line prompt?

No error popup is shown.

Naively speaking: may be this is because cefclient.exe is a substantive exe, 
while python scripts rely on cmd.exe during execution and throw an uncaught 
exception when it terminates?

Have you tried running some other Python GUI app, for example a wxPython 
app from command-line prompt and whether the error also appears?

I have tried a simple GTK widget 
(http://ralph-glass.homepage.t-online.de/clock/clock.py) and a set of PySide 
examples (https://github.com/PySide/Examples). They all open a DOS box in 
Windows, along with application window. Being closed, this DOS box produces no 
errors.

Cannot you reproduce my error on your environment?

Right now I hang out more on Ubuntu (I really loved their font smoothing,
it's relaxing for my eyes), but when I switch to Windows I will try to
debug this thing. I remember this error happening to me too in the past,
but it's not much priority, as this only affects when developing your
application, right? Your user won't launch the appplication from the
command line?

In principle, you're right. However, the feeling of bug out there on Windows is 
nasty :)
