6 JCK1.4a-runtime tests fail on JDK1.5.0-b08. 
The tests pass with JDK1.4.1 (tested with b21), JDK1.4.2 (tested with b26).

EVALUATION Will investigate; suspect change in gcc version or flags on Linux itanium is the cause. ###@###.### 2003-06-18 Similar failures reported in 4910006; suspect common cause. ###@###.### 2003-08-26 See analysis in 4910006. ###@###.### 2003-08-28 As discussed in detail in the comments for 4910006 this does *not* appear to be a C compiler flag issue. When I linked the generated *.o files with a C program, they returned the proper results. ###@###.### 2003-09-05 This may be related to when we shifted OS to build on from 7.2 to Redhat AS 2.1.. Not sure of the date/build integration that we switched to the new OS to build on.. ###@###.### 2003-09-08 I've tested this on Redhat 7.2 and it reproduces the same crash.. I've tested B06 and all is well. B07 was a dead JVM build. However JDK did get updated. I've taken a b06 JVM and plugged into a B07 JDK and test fails. Thus looking like libraries issue change and not JVM.. ###@###.### 2003-09-09 I tested a B08 JVM and plugged into a B06 JDK and the test passed. This is not a VM issue.. ###@###.### 2003-09-09 Since the generated object files produce the correct result when used in a C program, the problem is neither with the object files nor the underlying source code. This implicatese the jni layer. ###@###.### 2003-10-24 As it turns out, it was just a compile flag problem after all. ###@###.### 2003-11-03
