Follow-up Comment #13, bug #58926 (project octave):


@OP and @Kai: I recommend that the problem be documented in the Octave manual
rather than the wiki. Would the above location be suitable? The problem occurs
outside Octave's code base so perhaps calling it "Known Incompatibility wth
MKL" would be better than "Known Bugs". I don't know enough about MKL to
represent that it affects only Debian-based systems.

@OP: regarding the test suite failing, could you include the excerpts from
test/fntests.log showing where Octave crashed when used with MKL? Please do
this for both cases, without and with the export technique. We cannot promise
that Octave can be made sufficiently bulletproof against external library
architecture but we can certainly document it and list workarounds.
