Hello again @Ed-Enspectra,
You seem to suffer from the same issue as the one reported in SonarLint CFamily Errors - #11 by JolyLoic.
We don’t correctly recognize your compiler (could you please tell us its exact version?) and as a consequence, we are missing data during the analysis which leads to a crash.
Could you explicitly define in your build the macro __SIZEOF_POINTER__ to the right value for your architecture (usually 4 or 8), this should work around the issue (and don’t forget to remove the sonar.cfamily.reproducer property). Let us know if this works!
I also added your case to [CPP-3550] - Jira
