Crash in filter_check_list::new_filter_check_from_fldname due to filter_check_list being null #2734
Description
Describe the bug
After building sysdig-0.41 with libs-0.21.0, running many (not all!) Lua chisels crashes.
sysdig -c netstat works, sysdig -c iobytes does not, repeatably.
Running sysdig and csysdig by themselves seems to work fine.
How to reproduce it
- build 0.41.x with libs-0.21.0 and
-DWITH_CHISEL=ON - run
sysdig -c iobytes
Expected behaviour
Working chisel execution
Environment
Gentoo Linux, building from source with -Og -ggdb3 -fno-omit-frame-pointer -fno-strict-aliasing. Tested with both gcc-15 and clang-21.1.7.
