Signer segfault for 6 or more -v options

When running ods-signerd -d -vvvvv -1 there is no problem; adding another -v option (or even more) causes a Segmentation Fault.

Probable cause is supplying wrong arguments to a vprintf().

GDB dump follows.

Program received signal SIGSEGV, Segmentation fault.
