I'm trying to use KDevelop to debug the "gcc-8.2" compiler. I download the code for "gcc-8.2" and built it with "make". "gcc-8.2" seems to run fine and I can debug it with "gdb", however when I import the "gcc-8.2" project into KDevelop it often throws a Segmentation fault and (core dumped). When I open the project the CPU usage goes up to 100% for about 10 minutes, the KDevelop GUI hangs then finally in throws a segmentation fault (see below error).

My assumption is that the hanging KDevelop is the parser trying to parse the project. Is this correct?

How would I go about resolving/debugging this issue?

You help is greatly appropriated,

Thank you,
Stewart
