Comments
EVALUATION I think this might be a duplicate of 4755500. That is the only known recent problem with NaN handling in C1. This fix has been integrated as of 1.4.2 b04. We'll try to find some Cyrix hardware to test on but if you could get this build to the customer (located in /java/jdk/1.4.2/re/promoted/beta/b04/binaries/) and confirm that that fixes the problem then please update the bug. ###@###.### 2002-10-31 The customer has verified that the fix for 4755500 fixes this problem. ###@###.### 2002-12-10
