The crasher bugs go away from release 4.1.0 when never running with
-fprofile-use and -fprofile-generate simultaneously.
There is another 'checksum mismatch' issue with PowerDNS:
base64.cc: In function âchar<unnamed>::B64Encode1(unsigned char)â:
base64.cc:220: error: coverage mismatch for function
â_ZN38_GLOBAL__N_base64.cc_00000000_B36B9A3210B64Encode1Ehâ while reading
counter âarcsâ
base64.cc:220: error: checksum is 913e4cf0 instead of e0c8a426
base64.cc: In function âchar<unnamed>::B64Decode1(char)â:
base64.cc:220: error: coverage mismatch for function
â_ZN38_GLOBAL__N_base64.cc_00000000_B36B9A3210B64Decode1Ecâ while reading
counter âarcsâ
base64.cc:220: error: checksum is 93e2f130 instead of e21419e6
These go away when I delete the relevant .gc* files.
