Fixing crash when core logging was enabled

The operator=() function tried to use the "=" operator to copy the
entire structure at once, which of course called the same function
again, leading to infinite recursion, and thus, segfault.

Worked around this braino by simply copying each field individually,
forgoing the convenience of copying the structure as a whole.

Tested: Use of the core logging feature no longer crashes
