[Bug java/15769] New: ICE: seemingly infinite recursion through gimplify_expr

[green at redhat dot com]

Here's another case of blowing the stack.  I found this when building xalan from
rhug.  No small test case yet.  I can't seem to find a work around.

I almost think this is the same problem as PR 12454 which is for C++ but still the same problem.

Confirmed, this is most likely the same bug I fixed in the C/C++ front-ends in that their convert to 
truth value does not work right, I will look into it.

It is not seemingly infinite loop, it is an infinite loop.
