Great that you found a way to get it working.
I think the problem you faced with 128M is that
it creates one big transaction using 128MByte of
information from mysqldump file. So when
decreasing this to 16M you decreased the size
of the transactions to a manageable size.

Disk pages involved in a transaction is bound to
the Disk Page Buffer until the transaction is
committed. So large transactions require a very
large DiskPageBufferMemory.

However it is still a bug that this causes a crash.
It should cause a transaction failure, but not a
crash.
