RPi get_version error with flrig 1.3.42

[mdblack98]

trying this anyway. The first issue I hit using WSJT-X v2.5.0 RC6 and the version of flrig in the Raspberry Pi OS repos, which is 1.3.42, is this error on initialization ("Settings->Radio->Test CAT"):

Hamlib error: Feature not available
flrig_open: get_version failed: Feature not available
flrig.c(511):read_transaction return(0)
flrig.c(594):flrig_transaction return(11)
flrig.c(594):flrig_transaction return(11)flrig.c(801):flrig_open return(11)
rig.c(1026):rig_open return(11) while opening connection to rig

I take that back, perhaps I can help here. I tried using "Settings->Radio->Mode->Data/Pkt" in WSJT-X and got this crash in the Hamlib flrig back end:
Thread 15 "QThread" received signal SIGSEGV, Segmentation fault.

Seems the index on madeMap is not being bounds checked. This was using your patch for the flrig version check applied to the Hamlib-4.3 branch at commit bacb20a .
