New releases 0.3.14-1 of
openblas (source)
libopenblas (dinamic library)
are available in the Cygwin distribution :
CHANGES
Last upstream release bugfix and performance improvment
https://github.com/xianyi/OpenBLAS/releases
OpenBLAS will now provide enough buffer space for at
least 50 threads by default.
DESCRIPTION
OpenBLAS is an optimized BLAS library based on
GotoBLAS2 1.13 BSD version and further extended.
OpenBLAS is licensed under the 3-clause BSD license.
HOMEPAGE
http://www.openblas.net/
CYGWIN NOTES
1) As BLAS it is around 5-10 times faster than Netlib reference,
included in the liblapack0 package.
2) No devel package is provided as liblapack-devel already provide
the needed headers and import.
Openblas is fully compatible with Netlib BLAS.
3) libopenblas consist of a single file
/usr/bin/cygblas-0.dll
that will precede in PATH the liblapack0
/usr/lib/lapack/cygblas-0.dll
and used instead. Removing libopenblas will restore the
usage of Netlib BLAS
4) CPU architecture covered up to now

After upgrading libopenblas from 0.3.12-2 to 0.3.14-1,
octave 5.2.0 crashes on plot command in 64 bit environment.
In 32 bit cygwin (WoW64), this does not happen. Reverting
libopenblas to 0.3.12-1 resolve the issue.
octave:1> plot([])
fatal: caught signal Illegal instruction -- stopping myself...
Illegal instruction(core dumped)
My environment:
OS: Windows 10 20H2 (64 bit)
CPU: Inte Core i7 870 (Lynnfield)
[yano@Express5800-S70 ~]$ cygcheck -c cygwin octave libopenblas
Cygwin Package Information
Package Version Status
cygwin 3.2.0-1 OK
libopenblas 0.3.14-1 OK
octave 5.2.0-1 OK
By starting octave-cli in gdb, it stops at vmovaps instruction
in gemm_(). IIUC, vmovaps is an AVX instruction which is not
supported by Core i7 870.
In another PC with Core i7-4790 which supports AVX, the issue
does not occur.

Hi Takashi,
maybe is time to build the 0.3.15 ....
https://github.com/xianyi/OpenBLAS/releases
x86_64:
added support for Intel Control-flow Enforcement Technology (CET)
reverted the DOMATCOPY_RT code to the generic C version
fixed a bug in the AVX512 SGEMM kernel introduced in 0.3.14
fixed misapplication of -msse flag to non-SSE cpus in DYNAMIC_ARCH
added support for compilation of the benchmarks on older OSX versions
fixed propagation of the NO_AVX512 option in CMAKE builds
fixed compilation of the AVX512 SGEMM kernel with clang-cl on Windows
fixed compilation of the CTESTs with INTERFACE64=1 (random faults
on OSX)
corrected the Haswell DROT kernel to require AVX2/FMA3 rather than
AVX512
give me some time, openblas is a bit time consuming
Regards
Marco

Thanks for the information.
I have built openblas 0.3.15 locally, and confirmed that
it works fine with Core i7 870 (Lynnfield).
I will test it if you provide the test version of 0.3.15.
P.S.
The same issue happnes also with Xeon X5680 and v0.3.14.
