This makes no sense. Your test program does not refer to the itest facilities. There is single testing tool involved as well. Something seriously screwing up the stack.
Can you try to go step by step in the debugger?
I did. The stack gets corrupted when returning from cfc::operator/<double, 2, int> at tiny_vector.hh:182. The stack looks fine and then gets corrupted after one gdb "step". See attached gdb session transmission. I cannot imagine how this trivial function could corrupt the stack. How to debug this in more detail? I tried objdump -tD test_all >test_all.dis but I cannot find in test_all.dis the addresses mentioned in the traceback (e.g. 0x000000000047d43f)
Can you also try build UTF as external library?
What would that help? The error also appears when I link dynamically against the library provided in Debian (only the backtrace is less useful).
