Debugger and application not starting

[SeanOMik]

Brief Issue Summary

I'm trying to debug a project but when I click the debug button, nothing happens. I took a look at the logs but it doesn't really seem like anything happens. I've tried gcc and clang and gdb and lldb-mi all with the same results.

Additional Information

I took a look at the (non-debug) log file and it doesn't seem like it even tries to start and debug the program:

We're not sure what's happening here. The only thing that stands out is some of the environment variables with really long values. @WardenGnaw, do you know of any issues with running the debugger when there are a lot of environment variables or if they have really long values?

Yep, this is specific for lldb-mi. There is an open PR to fix it but the maintainers have not accepted it yet.
