Thread: Program terminates before completion with no event, crash or stackdump

Greetings,

I have a windows C program problem that has me baffled. The section of the code in question is doing a recursive loop to search through a directory structure. The program (on one machine) doesn't complete. There is nothing in the event logs and no crash file or stackdump.

I added a print statement to see where it might be failing. The last entry in the log file is not even a complete entry.

Here' the snippet of code:

Code:

		
// if this is a directory, call comp_files recursively, 
// unless it is a Junction point, which we don't want to recurse		
if ( S_ISDIR(fileStat.st_mode) )
{
	if (S_ISLNK(fileStat.st_mode)) //if junction point, continue to next entry
	{
		continue;
	}
	else
	{
		sprintf(nextSrcDirCyg, "%s%s", srcDirCyg, shadDirEntry->d_name);
		sprintf(nextShadDirCyg, "%s%s", shadDirCyg, shadDirEntry->d_name);
		strcat(nextSrcDirCyg,"/");
		strcat(nextShadDirCyg,"/");
		//recursively call comp_files with new directory name
		comp_files(nextSrcDirCyg, nextShadDirCyg);
		sprintf(logstring, "returning from recursive call for directory %s", nextShadDirCyg);
logprint(logstring);
fflush(locallogfile);
	}
}

Here are the last few lines from the log. Note that the last line of the log is not even complete in spite of a fflush to the log.

Any suggestions on how to diagnose this will be greatly appreciated.

buffers are 500 characters

Code:

	char nextSrcDirCyg[500];
	char nextShadDirCyg[500];

Logprint is very simple...

Code:

int logprint(char *print_str)
{

	lt = time(NULL);
	now = localtime(&lt);
	strcpy(asciiTime, asctime(now));
	strlength = strlen(asciiTime);
	asciiTime[strlength -1] = '\0';
	fprintf(log_file, "%s   %s\n", asciiTime, print_str);
	return(0);
}
