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.

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
