I create a small patch for this (just change one line and one little
value). The main problem is in the src/util.c code.

I viewed mc4.6.1pre1 which contains a segfaultable code with atol. That
was fixed in 4.6.1pre4 to use strtoll and check if 

The old code in 4.6.1pre1:

*line = atol(p);
p = strchr (buf, ';');
*column = atol (&p[1]);

The new code in 4.6.1pre4:

*line = strtol(p, const_cast(char **, &p), 10);
if (*p == ';') {
        *column = strtol(p, const_cast(char **, &p), 10);
        if (*p != '\n')
                *column = 0;
        } else
        *line = 1;

We see that there is a check for ; . If found then go and strtol p to
column. But. With this code the column got something like this as
value : (if in filepos : /xx.txt 12;20)

;20 

So the bad ; stays there and column goes to 0 and editor can not set
cursor to ';20' 

The fix is included. Need *column = strtol(p+1, const_cast(char **, &p),
10);

I attached this small patch against 4.6.1pre4

I hope this is good way to fix this problem, if not, please someone
correct out that :)
