it does not look like an uncaught exception. Maybe someone actually
called 'abort'? To investigate, I would try the following steps:

1. Place an infinite for loop in the 'abort' function, which is located
   in 'base/src/lib/cxx/misc.cc',
2. Start the test on base-linux,
3. Look for the spinning thread via 'ps -eLf | grep Genode',
4. Attach GDB to the TID of the thread (the one that has the highest
   CPU load), and
5. From within GDB, take a look at the backtrace via the 'bt' command.

Cheers
Norman
