--- Comment #2 from Vladimir Mezentsev <vladimir.mezentsev at oracle dot com>

I have fixes for these runtime errors:
  load of value 4294967295, which is not a valid value for type 'Cmsg_warn'
  null pointer passed as argument 2, which is declared to never be null
  load of value 4294967295, which is not a valid value for type 'ProfData_type'
  load of value 4294967295, which is not a valid value for type 'ProfData_type'
  member access within misaligned address 0x00000357583c for type 'union
Value', which requires 8 byte alignment
  reference binding to misaligned address 0x00000357583c for type 'long
unsigned int', which requires 8 byte alignment


I see other errors like:
 member call on address 0x000003192cf0 which does not point to an object of
type 'Vector'
These errors look like a bug in libubsan.
I don't see anything wrong in gprofng.
