Trying to install py-numpy, I tried both the OPENBLAS and the NETLIB options.

OPENBLASS does not even build (it dies while testing itself):
gfortran13 -O2 -march=native -Wl,-rpath=/opt/lib/gcc13 -O2 -m128bit-long-double
-Wall -frecursive -fno-optimize-sibling-calls -m32  -msse -msse2 -msse3 -mssse3
-msse4.1 -O2 -m128bit-long-double -Wall -frecursive -fno-optimize-sibling-calls
-m32  -msse -msse2 -msse3 -mssse3 -msse4.1 -fno-tree-vectorize 
-Wl,-rpath=/opt/lib/gcc13  -L/opt/lib/gcc13 -fstack-protector-strong  -o dblat3
dblat3.o ../libopenblas_nehalemp-r0.3.25.a -lpthread -lgfortran -lpthread
-lgfortran -L/usr/lib  -lc
OPENBLAS_NUM_THREADS=1 OMP_NUM_THREADS=1 ./sblat1
gmake[1]: *** [Makefile:30: level1] Bus error (core dumped)
gmake[1]: *** Waiting for unfinished jobs....

The BLAS/CBLAS/LAPACK (NETLIB) don't bother with self-testing and install.
However, trying to use even load them (such by running "import numpy" inside a
Python script) crashes too.

In all cases the crash is inside:
#0  0x2845b346 in _gfortran_transfer_complex128_write () from
/opt/lib/gcc13/libgfortran.so.5
[New Thread 28a12000 (LWP 115657/<unknown>)]

I tried rebuilding everything with both gcc13 and 12 -- the crash is the same.

SIGBUS suggests a misalignment of input arguments -- perhaps, something ought
to be aligned at 128-bit, and is not (because i386).

My CFLAGS contain -march=sandybridge and my FFLAGS use -march=native instead.

The CPU-features are listed (in /var/run/dmesg.boot) as:
CPU: Intel(R) Core(TM) i5-9500 CPU @ 3.00GHz (3000.11-MHz 686-class CPU)

However, this is a VM running under Oracle's VirtualBox supervisor.

According to OpenBLAS' Freshports-page, the port builds on i386 -- but it is
unclear, which version of gfortran it uses and which optimization flags.
