Description

Running rootn.exe from ROOT 6.30.04 should bring up the ROOT prompt, but instead crashes instantly on startup.

It works fine with older versions of ROOT (6.28, 6.26).

Reproducer

• Install precompiled ROOT 6.30.04, downloaded from root.cern, on RHEL8 or 9.
• Run thisroot.sh to set up the runtime environment
• Type rootn.exe
• Hard crash

Transcript of session on RHEL8:

This works without error with ROOT 6.26.14 and 6.28.12 on the exact same machine. Running plain root 6.30.04 also works, of course. Only rootn.exe seems affected.
