regex.d(6050): not enough preallocated memory

[Paul]

I am trying to see if all regex matches in one file are present 
in another file.
The code works; but, part way through the nested foreach(s) I get 
the error listed in the subject line.  I would think this error 
would come up when the Regex expressions were executed not when 
I'm iterating through the resultant matches.

Is there a better way to do this or can I just allocate more 
memory?
Thanks.

// Execute Regex expressions
auto uniCapturesOld = match(uniFileOld, regex(r"^NAME   = 
(?P<comp>[a-zA-Z0-9_]+):*(?P<blk>[a-zA-Z0-9_]*)","gm"));
auto uniCapturesNew = match(uniFileNew, regex(r"^NAME   = 
(?P<comp>[a-zA-Z0-9_]+):*(?P<blk>[a-zA-Z0-9_]*)","gm"));

// Iterate through match collections to see if both files contain 
the same matches.
     foreach (matchOld; uniCapturesOld) {
         cntOld++;
         found = false;
         foreach (matchNew; uniCapturesNew) {
             cntNew++;
             // Following line is for troublshooting.
             writeln(cntOld,"  ",cntNew,"  ",matchOld.hit,"  
",matchNew.hit);
             if (matchOld.hit == matchNew.hit) {found=true;break;}}
         if (!found) writeln(cntNF++," ",matchOld.hit," not 
found);}
