One additional observation. It seems that the static build does not crash, =
just
the shared build.

>>From the build log, we have for the shared build that crashes:

sh4-linux-gnu-gcc -pthread -c -Wno-unused-result -Wsign-compare -DNDEBUG -g
-fwrapv -O3 -Wall -g -fdebug-prefix-map=3D/<<PKGBUILDDIR>>=3D. -fstack-prot=
ector
-Wformat -Werror=3Dformat-security    -std=3Dc99 -Wextra -Wno-unused-result
-Wno-unused-parameter -Wno-missing-field-initializers
-Werror=3Dimplicit-function-declaration -fvisibility=3Dhidden=20

time
-D_FORTIFY_SOURCE=3D2  -fPIC -DPy_BUILD_CORE -o Objects/longobject.o
../Objects/longobject.c

For the static build, which did not crash in my test, we have:

sh4-linux-gnu-gcc -pthread -c -Wno-unused-result -Wsign-compare -DNDEBUG -g
-fwrapv -O3 -Wall -g -fdebug-prefix-map=3D/<<PKGBUILDDIR>>=3D. -fstack-prot=
