It is similar in LLVM, where it works against statically linked .a files
with sanitizers. For .so, I can observe similar information about
DEADLYSIGNAL without detailed information.
I will try to fix it in LLVM first.
I noted that FreeBSD people has similar issues, caused e.g. by the link
order of libraries (libthr vs libc).. not sure what's the reason in NetBSD.
