@thynquest is this still an issue for you, @thynquest ?

[thynquest]

Hello
Yes this is still an issue for me. last time I checked, when I launched the debug mode I get a segmentation fault. meanwhile I have switched to ipdb (which is not that comfortable btw)

Thank you

[DonJayamanne]

@thynquest
Please could you try debugging using the experimental debugger.
All you should really have to do is go into launch.json and change the setting "type"="python" to "type"="pythonExperimental"

[thynquest]

Hello DonJayamanne and sorry for the delay
I tried the python exprerimental and it does work. what is the difference with this option compared with the previous one ?
Anyway I'll keep doing some tests to make sure it works well and I will let you know if anything comes up
Thank you for your help

@thynquest the experimental debugger is PTVSD 4 while the "normal" debugger is PTVSD 3. Since PTVSD 4 is still in alpha we have not made it the default yet, but once it's stable we will be switching versions.
