Subject: [Bug translator/4886] stap should validate debuginfo files

Just a note: this likely wouldn't help the kernel case (where vmlinux is
unstripped), but for modules, it may help to change src/tapsets.cxx's
initialization of debuginfo_path to have a "+" instead of "-" at the front.
That activates (weakish) CRC checking of the debuginfo against the stripped
base file.
Just in case, would you mind testing that change with your wrong-vmlinux
scenario?
diff -r1.205 tapsets.cxx
668c668
< static char debuginfo_path_arr[] = "-:.debug:/usr/lib/debug";
---
> static char debuginfo_path_arr[] = "+:.debug:/usr/lib/debug";
