Thank you for your report, but we currently don't have resources to investigate crashes in old versions of Nmap that may already be fixed. Please upgrade to Nmap version 7.80 and try that. If you still get a crash, please open a new issue with full details like you provided here. If you are able to post a gdb backtrace so we can see where the crash is in the code, that's even better. But even crash reports without this (but with the latest version of Nmap) are useful. Thanks!
