Created attachment 22397
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=22397
preliminary fix for problematic assert

Simply splitting the && components of the assert into two separate asserts
solves the bootstrap problem for me on armv5tel-linux-gnueabi.

The problem was introduced sometime between 20101016 and 20101023.

I think this warning should be deleted or moved to the front-end. There should
be no warnings in fold-const.c as much as this is possible. There is already a
similar warning in Wlogical-op in c-common.h but it seems it doesn't cover this
case. It should.

Fixed when the dupe PR46456 was fixed.

This is a duplicate of a fixed bug (PR46456), so marking RESOLVED DUPLICATE.
