Open JDK8 fast-debug : crashes on Solaris Sparc T4 machines

[Baesken, Matthias]

I noticed when building Open JDK 8 fast-debug with Sun Studio 12 on Solaris Sparc,
the VM crashes early when executed on T4 based machines (both T4 based Solaris Sparc10 and 11 machines);
I cannot see the issue on older Sparc processors or Fujitsu SPARC64.
The  Crashes look like this :

When building with Sun Studio 12u1 (instead of 12) the crash does not occur, see :

  <maindir>/results/SS12u1/images/j2sdk-image/bin/java -version
openjdk version "1.8.0-internal-fastdebug"
OpenJDK Runtime Environment (build 1.8.0-internal-fastdebug-d040975_2014_02_12_15_29-b00)
OpenJDK 64-Bit Server VM (build 25.0-b69-fastdebug, mixed mode)


Is this a known issue with SunStudio12 build results on T4 Processors ?

I changed the used optimization flags in the fast-debug build from  -xO4  to -xO2 and the problem disappeared.
Could this  be done in the configuration  when SunStudio 12 is detected ?

Thanks, Matthias
