Backtrace is here: g++ pr95693.C -fsanitize=undefined -g && ./a.out pr95693.C:17:22: runtime error: reference binding to null pointer of type 'int' #0 0x4011fb in Derived::Derived() /home/marxin/Programming/testcases/pr95693.C:17 #1 0x401135 in main /home/marxin/Programming/testcases/pr95693.C:24 #2 0x7ffff7147cc9 in __libc_start_main ../csu/libc-start.c:308 #3 0x401079 in _start (/home/marxin/Programming/testcases/a.out+0x401079) I'm not a C++ expert, but it seems to me an invalid code.
