Which GCC version? Mind to share your config/defconfig?
There is one more reference of the same compile failure on the web, see [1].
numpy/core/src/npymath/npy_math_internal.h.src:482:12: internal compiler error:
Segmentation fault
return @kind@@c@(x, y);
^~~~~~~~~~~~~~~
Stating 'Bug does not occur when using -O0 on GCC 8.2.0 and does not occur at
all with GCC 9.1.0', mind to try a different compiler and/or optimization
setting?
Regards,
Peter

Config used when encountering numpy segfault
Attached my .config (compressed because too large for bugzilla).
I started from configs/raspberry3_64_defconfig and added the stuff I need.
About GCC version I am not sure which one you want... So I have these:
$
/home/buildroot/buildroot201907numpySegFault/output/host/bin/aarch64-buildroot-linux-uclibc-gcc
--version
aarch64-buildroot-linux-uclibc-gcc.br_real (Buildroot 2019.05) 7.4.0

Thanks for the info/config...
With make menuconfig under Toolchain-->GCC compiler Version you
can select different versions, e.g.
- gcc 4.9.x (works)
- gcc 5.x (untested)
- gcc 6.x (untested)
- gcc 7.x (your/default selection, numpy segfault)
- gcc 8.x (numpy segfault)
Or in case you use buildroot master from git
- gcc 9.x (works)

OK for the workaround. So you mean it is intrinsic to the gcc compiler and will
be fixed in the next major buildroot release (2019.08)? If so it is fine for
me. Thanks for the help.

Update:
- gcc 5.x (works)
- gcc 6.x (numpy segfault)
Yes, gcc-9.1 support was added already on git master (see [1]) and will land in
the next buildroot release...
