So, given that gcc 4.1.2 is really ancient, I've tried building 10.2 using gcc
9.3.0 instead (but still inside the Docker container). This builds fine, and in
fact I'm happy to go with this workaround.

However, might be worth noting somewhere that gcc 10.X cannot be built with gcc
4.1.2.

cheers,

Rich

Can you run
gdb --args ./cc1 -quiet -fself-test=../../gcc/gcc/testsuite/selftests /dev/null
-o /dev/null
and do

It's worked in 9.2, 9.3, and earlier releases; but not in 10.1.

If I try the build outside the Docker container, it works fine. So, there's
something about the Centos 5.11 toolchain/libraries that make it break.

Did GCC 10.1 work or any older version you tried to build this way in the past?
