(Serious) sparc/solaris EH problem

(Serious) sparc/solaris EH problem

[Teemu Torma]

I think the following problem should be corrected before the release.
If compiled with -O, i is not zero as one would expect.  The problem
does not happen if using sjlj exceptions, or if not optimizing.
I suspect that the register gets lost somehow.

$ c++ -O eh.cc
$ ./a.out
1: i = 0
2: i = 1
3: i = 1
