Problem running gtags on Drupal

[Arne Jørgensen]

Hi,

When I'm trying to generate tag files for Drupal I run into this error
message (and exit status 2):

 input buffer overflow, can't enlarge buffer because scanner uses REJECT


I narrowed the problem down to one file in Drupal:

 
http://drupalcode.org/project/drupal.git/blob_plain/30d1e719aa5e9a9ad66514078ca3b0975ddadc9c:/modules/system/system.api.php


And inside that file I narrowed the problem down to a large block
comment just before the hook_menu() function.

The block comment (lines 905-1209) is 305 lines long and removing any
~18 lines from the comment eliminates the problem.

Now, I don't have commit access to Drupal so I can't shorten the comment
by 18 lines myself and I'm not sure that would be the right solution
anyway :-)

Is this problem a known limit in gtags or something? Or is there some
way to get around the problem (besides using
:skip=modules/system/system.api.php)?

I'm using GNU GLOBAL 6.2 (and also tried 6.2.2 and 6.2.3) on Mac OS X
using Homebrew. I have a coworker running Ubuntu who experiences the
same problem (don't known his version though).

Best regards,
Arne
