Public bug reported:
The version of scalapack compiled in ubuntu and debian is limited to
2^31 elements. This is a known errata of scalack, please see
http://www.netlib.org/lapack/Errata/errata_scalapack_1.8.0.html
I applied that fix to the source package and recompiled and verified
that it fixed the issue.
Briefly, scalapack uses the Mptr macro to memory offsets. The arguments
to this macro are all integers and thus the macro may return a negative
integer for a large enough matrix. The fix is to generate an off_t type
instead.
