If the code segfaults there, it will try to throw a nullpointerexception which will trigger this assertion failure. No exceptions should ever be thrown from code that executes in a section in which interrupts are disabled." So you seem to have found a bug in kaffe's virtual machine code. Congratulations :) You might want to read FAQ/FAQ.debugging and FAQ/FAQ.jsignal if you want to fix the bug. dalibor topic
Re: Bug with Current KJC Compiler
From the error message below I can see that an assertion fails in a part of Kaffe that is written in C. Since KJC is entirely written in Java, it cannot be the reason of this problem - at best it demonstrates a bug elsewhere.

I am sorry but I don't have a solution. If I remember correctly, I also encountered that problem while working on the IA-64 port but finally I came up with a working version when I used a newer compiler (gcc-3.0.2) and a slightly different patch for jmp_buf save/restore. It would be nice if the problem was actually the KJC compiler. ;-) Bye, Gwenole.
