[Iain Woolf]

What is your environment (OS)?
 - Linux (Red Hat Enterprise Linux Server release 5.3 / kernel 
2.6.18-128.el5PAE)

Which version of GLOBAL are you using?

already fixed)

What did you do? (command line)

> gtags -v -f problem-file .
[Wed Aug 14 11:15:10 EDT 2013] Gtags started.
 Using default configuration.
 Using 'problem-file' as a file list.
[Wed Aug 14 11:15:10 EDT 2013] Creating 'GTAGS' and 'GRTAGS'.
 [1] extracting tags of define_too_long.h
Warning: symbol name is too long. (Ignored)[+3 ./define_too_long.h]
gtags: buffer overflow. strlimcpy(dest,

What did you expect from it?
 - I expected gtags to accept any symbol length that is supported by gcc
(this file compiles fine).

What was occurred? (as is)
 - buffer overflow in gtags. Empty GTAGS file is created.
