Public bug reported:
Hi
While building qemu statically, I get a SEGV on startup when it calls
getaddrinfo() for the VNC listener; it turns out this is easily
reproducible with a small C test case when building statically.
gcc -O0 -o foo foo.c && ./foo
=> works
gcc -static -O0 -o foo foo.c && ./foo
=> segvs
(gdb) run
Starting program: /home/lool/foo
Program received signal SIGSEGV, Segmentation fault.
