That was one of the things I want to do to investigate further, but I
want to be more selective, perhaps compiling only that file without
optimization. I'm still looking for a way to accomplish that.
I did get a warning from that file. This is from the build log:
Compiling
/.../build/sparcv9/hotspot/src/os_cpu/solaris_sparc/vm/os_solaris_sparc.cpp
cc1plus: warning: command line option '-std=gnu90' is valid for C/ObjC but
not for C++

/.../build/sparcv9/hotspot/src/os_cpu/solaris_sparc/vm/os_solaris_sparc.cpp:256:16:

Of course, the warning may not mean that the compiler misinterpreted
the code. The real problem may even be someplace else.
