OK, that's definitely not the problem I thought it might have been.
Can you run maple under qemu, adding
    -D qemu.log -d in_asm,out_asm,op,exec,int,cpu,guest_errors,unimp
on the command line?

http://www.mediafire.com/download/ge611be9vbebbw7/qemu.log

That log is interesting because the logging for the last TB
we try to execute has the "IN" and "OP" sections but no "OUT",
suggesting we segfault in the process of trying to translate
that TB.

Unfortunately I haven't been able to reproduce your problem
locally yet (apt-get doesn't crash, anyway). What configure
options did you pass to QEMU? Does the crash still happen
if you build qemu with --enable-debug (which might get us
more useful ARM backtraces) ?

thanks

The crash does not happen if --enable-debug is added to the configure line (just tried again to be sure). My configure line is: "./configure --prefix=/usr --static --target-list=i386-linux-user" or "./configure --prefix=/usr --static --target-list=i386-linux-user --enable-debug"
