Sorry, I'm a little in a hurry...
The diff is rather big, so just
export CVS_RSH="ssh"
cvs -z3 -d:pserver:[EMAIL PROTECTED]:/sources/qemu co
-D "20051115" qemu
this should check out the last working version. I built it with GCC3
and it was running fine.

Thanks for the patch! I already browsed through the CVS history on
savannah, but it's a bit tricky because some code parts moved
between files when SMP support was added. Could you please provide
a complete diff to the last fully working CVS snapshot? According
to your patch, it dates back to September, right? I only looked at
the changes since the beginning of November.
The GDB output I posted last time was generated after I had removed
some 'inline' statements to find the correct code lines. The
following is the result from unmodified CVS:
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000010
0x00062f98 in tb_phys_invalidate (tb=0x8cad00,
page_addr=4294967295) at /Volumes/Data/build/qemu/exec-all.h:249
249 {
This is the path to the crash (each function calling the next one):
tb_invalidate_phys_page_range() [exec.c]
tb_phys_invalidate() [exec.c]
tb_reset_jump() [exec.c]
tb_set_jmp_target() [exec-all.h]
According to GDB, qemu crashes in the moment (or shortly after)
when tb_set_jmp_target() is called (line 442, exec.c). As I wrote
in my last post, the crash does not occur when cpu-exec.c is
compiled with GCC4 while everything else is compiled with GCC3.
Compiling only exec.c with GCC4 does not help. Since cpu-exec.c
includes exec-all.h through target-pcc/exec.h this could be a point
to start.
Already played around changing several pieces of the code - it does
not help - maybe I'm just too blind...

Jo.

(ie, before mp was commited)
I'm now scanning thru the changes in exec.c...
my guess is, that things stay as they are, since gcc4 is not a
target in the near future as stated many times. The GCC4 warnings
was only added, because there where a lot of annoying posts on the
list about "can't compile on GCC4". So GCC4 is only a
workaround :) for now. Thing is, that only qemu-system is working
when compiled by gcc4, qemu-user not.
