A completely unrepresentative poll among two C++ programmers showed that 50% thought it was a segfault, whereas the other 50% suggested it could be undefined behavior, deducing that from the knowledge that the behavior is different in Linux userspace and kernel.
Although I wouldn't call those two typical C++ programmers. They do security CTFs for fun, so they might have a broader knowledge about exploitable behaviors in C/C++ code.
