I suppose that shuJIT which crash with Swing is compiled
from source code by yourself.
Source code of current shuJIT, specifically code.c is
too sensitive to register allocation by C compiler. I'd
like to fix this character of the code.
You can examine whether you are suffering this problem
or not by looking at disassembled code of code.o
% objdump code.o
.....
00000000 <assembledCode>:
0: 55 pushl %ebp
1: 89 e5 movl %esp,%ebp
3: 83 ec 0c subl $0xc,%esp
6: 57 pushl %edi
7: 53 pushl %ebx
8: e8 00 00 00 00 call d <assembledCode+0xd>
.....
You may be suffering if you find the line containing
`pushl %esi'
around here.

I'll investigate this possibility, too.
