[Bug-indent] Segmentation fault when indenting strange file

[Ralf Engels]

Hi,
while testing my Maki decompiler I made an error and tried to indent a debug 
output.
You can imagine my surprise when I noticed that indent failed with a 
segmentation fault.

It didn't take long to notice that there is an error in function 
handle_token_colon line 878ff when adding something to an array (sorry, no 
comments can be found there).

I fixed it by adding check_lab_size as you can see some lines further in 
handle_token_preesc.

I think that further errors could be lurking around line 1720 where again 
*e_lab++ without check_lab_size.


Proposal:
1: write a function 

void add_label( char* label ) {
        check_lab_size();
        *e_lab++ = label;
}

and replace all direct *e_lab access.

2: Add some comments


BR,
Ralf
