Re: Fix 64-bit PR16923 on Solaris 10+/x86

Hi,

I am having a similar issue here. Please read the following.

I am getting a crash when a native exception through JNI is propagated to
Java. The source code is really simple and it just throws a native
exception. I think the process crashes when it tries to unwind the stack
after an exception is thrown. You can see the error below. One more thing,
it only happens when the native library is compiled on 64 bit arch, and it
does work successfully on 32 bit arch. I am using gcc compiler and stats are
mentioned below as well. Let me know if you need more information. One more
thing, this code works perfectly well in Linux systems and i could see one
compiler option "--disable-libunwind-exceptions" on Linux. Does this option
really play any role for these kind of exceptions ? Should we put this
option whiling building gcc compiler on Solaris box ?
