[Octave-bug-tracker] [bug #36211] bug: crashes and endless loops

[anonymous]

Follow-up Comment #4, bug #36211 (project octave):

I've been looking for a statement that clarifies whether DGELSD claims to
check the input (for infinity/NaN values) itself or expects the caller to take
care of this.

I could not find anything in the Lapack User Guide or in the source of
http://www.netlib.org/lapack/double/dgelsd.f, but here --
http://software.intel.com/sites/products/documentation/hpc/compilerpro/en-us/cpp/win/mkl/refman/lse/lse_intro.html
-- it says:

"Warning LAPACK routines require that input matrices do not contain INF or NaN
values. When input data is inappropriate for LAPACK, problems may arise,
including possible hangs."

So, maybe octave could do a call to "any_element_is_inf_or_nan()" like it
already does, for example, for svg () and eig ()?

Regards
Stefan Reiser
