Minimal library project
I have built a version of GNAT from svn trunk targetted at bare metal
arm-none-eabi. I know this isn't supported, but I've managed to do it using
some patches. The entire project can be found here:
https://github.com/Lucretia/tamp
The problem is, when building the stripped down RTS, I'm getting the following:

Exception name: SYSTEM.ASSERTIONS.ASSERT_FAILURE
Message: namet.adb:655
arm-none-eabi-gnatmake: INTERNAL ERROR. Please report.
I've also managed to re-create the error using the attached minimal files -
extract to the tamp directory:
PATH=/opt/tamp/bin:$PATH LD_LIBRARY_PATH=/opt/tamp/lib64:$LD_LIBRARY_PATH
arm-none-eabi-gnatmake -vP2 --RTS=../rts/boards/beagle -Ptest.gpr
obviously, modify PATH & LD_LIBRARY_PATH to where-ever you compiled the cross
compilers to.
