I have a fix by not never producing MAX_EXPR or MIN_EXPR in reassoc.

Here is a short testcase:
int f(int a, int b)
{
int i;
int c = a>=b?a:b;
for(i = 0;i<1000;i++) ; // Needed otherwise Jump threading gets in the way
int d = c>=a?c:a;
return d;
}

MAX_EXPR
:)
Reassiocation produces:
aWidth_29 = MAX_EXPR ;
w_30 = MAX_EXPR ;
From:
aWidth_29 = MAX_EXPR ;
w_30 = MAX_EXPR ;
The testcase you provided is undefined which is why it no longer ICEs in 4.3.0
