Hello,
I just tried with my Quectel RM520N-GL:
# qmicli -p -d /dev/cdc-wdm0 --nas-get-plmn-name=26201
malloc(): unaligned tcache chunk detected
Aborted (core dumped)
# qmicli -p -d /dev/cdc-wdm0 --nas-get-plmn-name=26201

# qmicli -p -d /dev/cdc-wdm0 --nas-get-plmn-name=11111
malloc(): unaligned tcache chunk detected

It seems to be 100% reproducable.
This just for info. I currently have not the need to use this command.
