Trying to run linux-user-test-0.3 from qemu.org. The programs produce
the expected output but always end up with a segmentation fault:
$ sparc64-linux-user/qemu-sparc64 ../linux-user-test-0.3/sparc64/busybox
BusyBox v1.6.1 (2007-10-20 10:22:43 EEST) multi-call binary

The ACLink bus has been removed.
The PL041/AACI driver now directly control the LM4549 codec driver.
The AC97 emulation in ac97.c has not been reused. Making the current
implementation sharable is not trivial and could bring regression
to other platforms.

Because I/O ports of VGA are fixed, so there can be only zero (which
is handled by -vga none) or one devices.

Disabling -Werror on 32-bit builds is of course a workaround, but the
right answer will be to see that the issues are fixed upstream.

Add a microbenchmark for coroutine create, enter, and return (aka
lifecycle). This is a useful benchmark because users are expected to
create many coroutines, one per I/O request for example, and we
therefore need to provide good performance in that scenario.
To run:
make check-coroutine
./c
QEMU is event-driven and suffers when blocking operations are performed because
VM execution may be stopped until the operation completes. Therefore many
operations that could block are performed asynchronously and a callback is
invoked when the operation has completed. This allows QEMU to contin
From: Kevin Wolf
Asynchronous code is becoming very complex. At the same time
synchronous code is growing because it is convenient to write.
Sometimes duplicate code paths are even added, one synchronous and the
other asynchronous. This patch introduces coroutines which allow code
that looks sy
To run automated tests for coroutines:
make check-coroutine
./check-coroutine
On success the program terminates with exit status 0. On failure an
error message is written to stderr and the program exits with exit
status 1.

This patch speeds up coroutine creation by reusing freed coroutines.
When a coroutine terminates it is placed in the pool instead of having
its resources freed. The next time a coroutine is created it can be
taken straight from the pool and requires no initialization.

@Serge,
I saw that. It doesn't happen when i extract source on local box via *.dsc
file and build with 64-bit glibc.
I would guess it was attempt to compile with 32-bit version of glibc. 32-bit
support on spice.v35 was dropped.
