PureBasic Forums - English

In both 5.70 and 5.71 the IDE runs until I attempt to create a new project. PureBasic app core dumps with a SIGSEGV as soon as I select Project/New Project menu option. checkinstall.sh works OK.

Ran it in gdb to see if I could tell what is happening. This is what I get at the console.

For what it's worth, 5.62 runs and doesn't crash on New Project. Haven't tested further.

I was able to get it to run by editing launch.sh for my system as below and using it to run the application. Not being an expert, I'm happy to find at least a way to run the app. I'll have to see what else fails as I build projects and compile files.
