Segfault when creating many child nodes

Hi @jholloc,
With the current master
branch I frequently get bad_alloc
exceptions and/or SEGFAULTS when initializing many child nodes on an HDC node.
Example program:
#include <hdc.hpp>
#include <iostream>
int main() {
HDC hdc;
for (int i=0; i<1024; i++ ) {
std::string child_name = "Child#" + std::to_string(i);
try {
hdc.get_or_create(child_name);
} catch (std::exception &ex) {
std::cerr << "Caught exception '" << ex.what() << "' at i = " << i << std::endl;
return 1;
}
}
return 0;
}
When I compile and run this program on the master
branch, this results in the program SEGFAULTing.
The last release (v0.21.0) doesn't have the same problem. After doing a git bisect, the issue seems to be this commit: 5fb812b
This commit touches a lot of logic, so I cannot pinpoint a likely cause..
