Looks like this problem is due to hard-coded -O3 and -O2 in Makefile.
Segfault is not happening when those options are removed.

Core dump running in a linux container with Debian 10 using -O3, -O2 or -O1.
No optimisations (-O0) corrects issue and can index sites

When I change the following to -O0, indexing works.

Onlyjob: -O3 is very unstable and causes segfaults all over (e.g. #172).

CC_OPT_ARG ?= -O2

So changing all instances of CC_OPT_ARG ?= -O2 to CC_OPT_ARG ?= -O0 should stop the core dump/segfault in Debian 10?

Still happening to me.
