[Wien] lapw2 SIGSEV (9.1)

[Laurence Marks]

The "fix" was to remove a -static option in the linking, at least for
the 32bit machines. (N.B., I would not recommend the options
-no-prec-div and instead would use -mpi -prec_div -ipo1; the options
you are using will be very slightly faster but at the expense of
accuracy, and -ipo1 is faster for execution and safe.)

I don't know what you meant by the "NO!" with respect to
/etc/csh.cshrc and ulimit. Even with a 64bit OS, depending upon
specific details of the OS (and these things are never standard) many
parameters such as stack-size limits, LD_LIBRARY_PATHS and other
environmental variables are not inherited from the calling shell.
