Covoar has been unable to run after upgrading to GCC 12 because by
default it generates DWARF5 debug info. Covoar uses libdwarf from
Elftoolchain to read the debug info, and libdwarf only supports DWARF
versions 2 through 4.
I submitted a ticket notifying Elftoolchain about this issue
(https://sourceforge.net/p/elftoolchain/tickets/611/).
At the moment, you can get coverage to run just by going into
rtems-tools/rtemstoolkit/elftoolchain/libdwarf/libdward_info.c at line
228 and changing
cu->cu_version > 4
to
cu->cu_version > 5
