Hello Chris,

thanks for the tests.

The crypt01 is a long running test.

I see also sporadic failures in the spintrcritical* tests on this BSP 
independent of the compiler.

The minimum test is an issue on all BSPs since the RTEMS tester has no 
way to figure out what to do since the test has no output. One option 
would be to use ELF files for the tester input with ELF notes for the 
test state, etc.

This can be fixed by using RTEMS_OBFUSCATE_VARIABLE().

Ok, good. Lets wait for the GCC 12.1 release.
