2. built using git: commit ba17add79a563bd1395dc05fa7309baffbcaa3ce (HEAD
-> master, origin/master, origin/HEAD)
All I did was clone it, run autogen, run configure with a prefix and make
install

==71159== Your program just tried to execute an instruction that Valgrind
==71159== did not recognise. There are two possible reasons for this.
==71159== 1. Your program has a bug and erroneously jumped to a non-code
==71159== location. If you are running Memcheck and you just saw a
==71159== warning about a bad jump, it's probably your program's fault.
==71159== 2. The instruction is legitimate but Valgrind doesn't handle it,
==71159== i.e. it's Valgrind's fault. If you think this is the case or
==71159== you are not sure, please let us know and we'll try to fix it.
==71159== Either way, Valgrind will now raise a SIGILL signal which will
==71159== probably kill your program.

** Process crashed **
5. Looks like "UNKNOWN workq_ops option 128" is the problem, but there
isn't a VKI_WQOPS_* define for 128...
