log: segv in a portable way

this piece of code creates a SEGV from logging code to verify a
bug fix at e3fe18a.

clang will delete the null-referencing code. so we need to either
- pass -Wnonull-dereference to $(CC)
- or use  __builtin_trap() offered by GCC/clang
- or use `volatile`
seems volatile is easier and probably more portable.

Fixes: #14856
