One of the following printf()s are trying to print a non-terminated
string (thus strlen(), inside, traps):

http://nxr.netbsd.org/xref/src/sys/kern/exec_elf.c?r=1.20#882

Fail is unusual due to kprintf_mtx, which is at IPL_HIGH, and protects
kprintf().  Trap at such level is not expected and triggers asserts a
bit earlier.
