    stream = fopen(theErrorFileName, "w");
    fprintf(stream, "%s%u%s", "Current byte-offset of file-pointer is: ", 69,
	    "                        \n\n\n");   

return value of fopen isn't checked. If path is invalid, crash.

How to repeat:
set DataDir in config.ini to something invalid (e.g. /pants... unless you have a /pants)

Suggested fix:
Gracefully exit with error

Code is common in 4.1, 5.0 and 5.1. Problem will exist in all (have reproduced on 5.1)
