Hi,
I upgraded my workstation from Ubuntu 8.04 to 9.10, and I got crash when running
java -version with IBM VME, drlvm works well, [1] is stack trace.
It crashed in zlib, and if I changed zlib optimization level from -O3 to -O2,
the crash never happened, so it seems some gcc aggressive optimizations can't
work with VME and cause the crash. So shall we change the default zlib
optimization level to -O2 to make it work with this popular distrubition?
$ gcc --version
gcc (Ubuntu 4.4.1-4ubuntu8) 4.4.1
