sample source file that causes the internal compiler error
compiling any cython-generated python3 extension causes an internal compiler
error using gcc 9.1.0 (on CentOS 7.6 x86_64).
the output for one of the failing modules, compiled with
gcc -v -save-temps -pthread -Wno-unused-result -Wsign-compare -DNDEBUG -g
-fwrapv -O3 -Wall -fdata-sections -fdata-sections -flto -march=native -s -fPIC
-I/opt/include/python3.7m -c _time.c -o _time.o -g0
is as follows:

<built-in>: internal compiler error: in build_common_tree_nodes, at
tree.c:10521
The resulting _time.i file contains only
# 1 "ti/cache/_time.c"
It should however be possible to compile the attached .c file with only the
python 3.7 headers.
Compiling the same source file using gcc 8.3 doesn't cause the internal
compiler error. If it helps I can send the .i file generated by gcc 8.3.
