GNU Global exhausts disk space

[Tu Do]

I tried to generate GTAGS database on Boost source code and then gtags keeps running forever, despite the source tree is only more than 100MB. The attached file is the boost directory in my /usr/include installed from Ubuntu. Here are the step to reproduce:

- Extract boost.tar.gz archive.

- Then run the command: gtags

- It keeps running forever until the OS pops a dialog box up saying that disk is out of space.

- Then running gtags is terminated; the thing is, disk space is not actually consumed.

If you cannot download the file from the email, you can download it here: http://www.mediafire.com/download/so40iih8ns2rpsz/boost.tar.gz
