This is an old report against version 3.6.4.  I'm going to close the report.  It can be re-opened if it is reproducible with the 4.0 release candidate.

This would be a problem with the MSVC Windows version.

On my MinGW Windows builds (w. OpenBLAS) I don't see a segfault with these commands.

Needs confirmation by other Windows users or devs.

There was an updated OpenBLAS dll posted to the mailing list a few months back, if that is still available you might try replacing your OpenBLAS library and see if it fixes the crash.

This may be a windows problem. Works correctly
in Fedora octave 3.6.4 and current devel. (x86_64)

Installed package: octave-3.6.4-vs2010-setup.exe
Library used: OpenBLAS
This code causes a crash:

x=[1i,1;0,1];
inv(x)

Error: Segmentation Violation.
There is no problem with the generic library.
