[Wien] lapw1.def fail -- invalid pointer

[Laurence Marks]

I've seen this with various code (not always Wien) and it is difficult
to track. Some possibilities are inconsistencies between
libraries/kernel and compiled versions, and/or virtual memory
problems.  There is no reason this a clear indicator of hardware
failure, although if you have that anything is possible!

My suggestion: don't do anything unless you have to unless you can
make it reproducible.
