Released block N1: already free
During an attempt to deallocate block number N1 on a file system, it was
discovered that the block was already free. This indicates an inconsistency
in the file system. Run fscheck.xrel on the disk immediately to attempt
to repair the disk.
Odd load address
The system was asked to load an .exec file to an odd address (68000 processors don’t execute code at odd addresses).
Bad header magic
The magic bytes in the header of an .xrel file were not present. Caused by
a misnamed or corrupted file.
Truncated xrel file
Something is wrong with the relocation table at the end of an .xrel file.
freemem(N1)
Somebody called freemem with an argument of N1 (N1 is in hexadecimal).
The address N1 does not correspond with the memory manager’s information,
so either N1 was never returned by getmem or getfmem, or some corruption
of memory has occured.
freemem(0xN1)[OxN2] returns 0xN3
The system attempted to free some memory which it used for internal purposes, and freemem returned the error value N3. The system called freemem
from address N2. The address which was being freed was N1. Caused by
corrupted memory.
