--------------------+-------------------------------------------------------
 (At least) one place in IOASCII assumes maxdim<=3 by only allocating 3
 entries of an array but then writing maxdim entries. The thorn TestArrays
 tests 4D arrays in its testsuite and while this seems to work on 64bit
 machines, it gives a segfault on 32bit machines (plus valgrind complaining
 loudly). Allocating maxdim entries (like also done elsewhere in the file)
 solves this problem, as indicated in the attached patch.
