error in globash.rc

[Marcello Nuccio]

The check for bash version in globash.rc of global-4.3.1 (but the same
bug is in version 4.1.1) fails if BASH_VERSINFO[1] contains letters.
I have bash version 2.05a.0(1)-release, and I get:

address@hidden:~/local/src/global-4.3.1$ bash --rcfile globash.rc
bash: 05a: value too great for base (error token is "05a")
Segmentation fault


The following patch should fix the problem:
