Err, I mean the 9745 testcase, sorry.

This contradicts what I have seen with a cross-compiler, and what David Edelsohn has reported. However, I should point out that there are 3 testcases in 9745. Maybe my patch doesn't fix all of them? Which one(s) did you try? Make sure you don't have any other patches applied that might skew the results, in particular my earlier alias.c patch.

I can confirm that your patch fixes libmcrypt, where 'make check' now passes. What isn't fixed is the minimized testcase pr11319.c. But even compiling this testcase with -fno-strict-aliasing still lets it fail, so I rather think your patch uncovers YALB (yet another loop bug)?

Franz.
