How to enable stack trace ?

[abhishek desai]

Hi,

I am using libgcj 3.4.6 cross compiled for a mipsel system. I am using
this in the interpreted mode. When I execute my program I get

Exception in thread "main" java.lang.NullPointerException
   <<No stacktrace available>>

Is there any way to enable the stack trace ?

This means that something truly awful has happened while trying to print
the stack trace, and libgcj has crashed.  This can be because of stack
corruption, or perhaps the stack unwinder doesn't work.  The only real
way to figure this out is to use gdb.
