Describe the bug:

[smartmontools]: The smartctl tool produces a "Segmentation fault" on exit. This happens regardless of arguments after the output seems to be correct and complete. Initially observed with smartctl -d sntrealtek -a /dev/sda but just printing the version produces the segfault. Help with smartctl --help segfaults on exit too.

Environment (please complete the following information):

• Entware feed: [armv7sf-k3.2]
• Device [Netgear R6300V2 router]
• Firmware version [dd-wrt r64210]

Output:

smartctl -V
smartctl 7.5 2025-04-30 r5714 [armv7l-linux-4.4.302-rt232-st71] (localbuild)
