"&" is probably creating its result on the stack, and there's not enough space
for a 20-million-character string on your stack, resulting in Storage_Error. You
can check the GNAT sources if you want to be sure.
You could allocate the space and copy the 2 strings in separately, similar to
what you do in your 1st test.
Do you really have 10-million-character strings, or are you allocating enough
for the maximum from VB? If the latter, you can allocate just the amount you
need. Ada is good at that.
