Which standard library do you use? MariaDB is a C++ project and uClibc 
does not fully implement thread local storage on Aarch64, which is used 
by C++ exception handling. C code works, C++ code dies with SIGSEGV on 
the first try/catch block. musl functions correctly and glibc should 
work.

Kind regards,
Andreas
