[Octave-bug-tracker] [bug #34822] Mingw panics on a simple complex product

[Tatsuro MATSUOKA]

Follow-up Comment #21, bug #34822 (project octave):

I have rebuild the OpenBLAS 



make CC=i686-pc-mingw32-gcc FC=i686-pc-mingw32-gfortran DYNAMIC_ARCH=1
TARGET=NEHALEM NUM_THREADS=4


The build reports are

 OpenBLAS build complete.

  OS               ... WINNT
  Architecture     ... x86
  BINARY           ... 32bit
  C compiler       ... GCC  (command line : i686-pc-mingw32-gcc)
  Fortran compiler ... GFORTRAN  (command line : i686-pc-mingw32-gfortran)
  Library Name     ... libopenblasp-r0.1alpha2.4.lib (Multi threaded; Max
num-threads is 4)



octave:1>  n=2000; A=randn(n); B=randn(n);tic; C=A*B; t=toc,
MFLOPS=2*n^3/t*1e-6
t =  0.96606
MFLOPS = 1.6562e+004
t =  1.0561
MFLOPS = 1.5151e+004
t =  0.97106
MFLOPS = 1.6477e+004
t =  1.1741
MFLOPS = 1.3628e+004
t =  0.95905
MFLOPS = 1.6683e+004 



The results were the mostly equaled to that were executed previously.

For my case, auto detection seems not to be effective.
