I'm wondering if there's a known problem with PPC linux-user. It
appears that static binaries work, but those that are dynamically linked
seem to always fail in the same way:

This fixes a compile error for a variable that wasn't changed (it was
previously renamed to make the variable more descriptive). It also adds
"#include " for prototypes of malloc() and free().

Qemu doesn't check socklen_t values before using them. If a value is
provided that is large (say -1) then qemu will merrily use it in
alloca() (which will blow the stack). The kernel checks all socklen_t
values for < 0 or > MAX_SOCK_ADDR.

Qemu doesn't exit with the proper code when dieing from an uncaught

the kernel filters values from exit() and _exit().

The linux-user getpriority() syscall goes through the libc wrapper.
This causes a problem because the libc wrapper remaps the return value

I have a series of patches to add *at() syscalls to linux-user. The
patches have minor inter-dependencies due to adjacent modifications in
some files.

Has anyone seen an insta-segfault with i386-linux-user qemu? I've
compiled qemu-0.9.0 as well as qemu-cvs (2007-09-18) with gcc-3.4 and
-fno-strict-aliasing on an amd64 and I get this:
./i386-linux-user/qemu-i386 --help

I've encountered what appears to be a race condition in arm-linux-user:
sometimes the program qemu is running will hang forever and sometimes it
will complete. After digging about there appears to be at least two
problems:
1) An initial cause of a SIGSEGV
2) The incorrect handling of the SIGSEGV
