Problem seems to be solved:
It was caused by an old-style sys_arch_mbox_fetch()
returning 0 instead of SYS_ARCH_TIMEOUT.

I'm very new to lwIP.
Just trying to implement lwIP for the Leon2 processor running the Open-Ethernet core under RTEMS 4.6. using the current lwIP from CVS.

Testing with "simhost.c", "apps/httpd.c", "apps/shell.c" etc.

Ping works fine in both directions, no errors, no packet losts.

But when I try to telnet the target system
    telnet 192.168.0.10
I'm failing with
    Assertion "pbuf_free: p->ref > 0" failed at line 575
    in ../../../lwip/src/core/pbuf.c

For http://192.168.0.10 the HTML-page is displayed, but nevertheless the system fail with the same message.

Any ideas ?

Thanks & regards,
Rolf.
