[Message part 2 (text/plain, inline)]

Hi Alex,

I rechecked the issue with my new hardware (got a new laptop meanwhile).
The issue does not occur for the files attached on the bug report anymore.

As I suspect that it has something to do with large memory allocation, I
produced some larger files
with an python script. I tested it on my machine still with etags (GNU
Emacs 23.1) and gave the files
to a collegue, who tested it with etags (GNU Emacs 24.3). On both etags
crashed for test_seg.c.
