Segfault on startup

[AntyMew]

Work environment

Questions	Answers
OS/arch/bits (mandatory)	Debian bullseye - Linux 5.4.0-2-amd64
File format of the file you reverse (mandatory)	N/A
Architecture/bits of the file (mandatory)	N/A
r2 -v full output, not truncated (mandatory)	segfault (current master, commit hash f715f01)

Expected behavior

No crash

Actual behavior

Passing any option or argument to r2 (as far as I've tested) results in a segfault. This is a regression from 4.1.1, which is working on my machine.

Additional Logs, screenshots, source-code, configuration dump, ...

You probably have mixed versions of libs or old plugins around. R2 works and starts perfectly fine

Resolved. I think apt was holding onto an old lib which I hadn't auto-removed yet
