bug: figuring out why a segfault occurs after we exit main.

ubsan:

/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/v1/vector:926:60: runtime error: applying non-zero offset 18446744073709551536 to null pointer
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/v1/vector:926:60 in
drv: SIGSEGV: Please report this on the GitHub issues page

why?

 - A bogus iterator gets passed to ::destroy inside the method.

next:

 - Debug that inside lldb.
