At first, I thought this was because of changes I made to the compiler, but I rolled back to Dec 16, 2020 before I had made any changes to the compiler, and tried again, with the same result:
I am thinking that this may be due to an ABI change in the linux kernel that I pulled with a recent 'sudo apt update ; sudo apt full-upgrade' .
I am not an ELF expert, so I'm not sure I can fix this, especially since I don't have a debugger that will work on the bootstrapped amacc executable produced by the compile commands above. If anyone can point me to a debugger that will work on amacc ELF files, I can try to make some progress
PS Just getting back to amacc work after a forced hiatus.
A recent problem has appeared:
