It stopped with a message saying "Memory allocation request failed", right?

The first argument is the size of the uvector, in this case in longs, e.g. about
4.25 megabytes.  The third argument is the subtype of the uvector, 62 indicates
you were making a hash table vector.

Hash table vectors have to hold both the key and the value, so are twice the
size of the number of entries in the hash table (plus a small overhead amount).

So the 3M memory available wasn't sufficient to create this hash table.  You can
fix it by either increasing your memory size (or decreasing the size of the hash
table).

%make-initialized-uvector is an internal function of MCL and therefore isn't
documented.
