Details:
Hi,
I run the following code snippet on Octave 3.6.4 compiled from source with the
--enable-64 option (according to
http://www.gnu.org/software/octave/doc/interpreter/Compiling-Octave-with-64_002dbit-Indexing.html)
on a large volume of data (4D NDArray of several GB).
The computation generates two child processes and things seem to be working
well until octave collects results for them. Then it terminates with a
segmentation fault. It also turns out that if the last assignment is dropped
(ie. I call > parcellfun(...) instead of > x = parcellfun(...)) octave does
not segfault but I cannot retrieve the result since the ans variable is absent
from the current scope.
Unfortunately the server on which I run this does not have debugging symbols
so I cannot easily investigate the cause (but I could provide the octave-core
file ~18 MB).
Thanks,
Shan
