------- Comment #3 from monaka at monami-software dot com 2010-01-29 03:21 -------
We can reproduce same ICE with Attachment #19745.
I got ICE in case like this.
$ cc1 -msx -g -O1 regex.i
but I didn't get any errors in case like this.
$ cc1 -msx -g -O0 regex.i -fipa-pure-const
So it's possible this issue is caused by static-var optimization.
