Actually I'm pretty confident this is not specific to s390 or SLES. I've
seen the same thing with a dump form a x86 system which had CA SEOS
loaded. It's just that in that case crash is able to create the necessary
memory region because the delta between the addresses is less than 1 GiB
(due, of course to the much smaller size of zone one). So it is still
potentially an issue for x86.

calculated as the last module name address minus the first observed
module address plus BUFSIZE. Is this guaranteed to be correct? The code
appears to be assuming the module symbol table is ordered by the address of
the symbol names. Is that guaranteed?
