About my coredumps problems at startup in Solaris 10 - 64 bits, I have
recompiled in debug mode and inspected core.

The problem root is in VSC_main, it isn't initialized and generates a
bus error in: vsl_wrap () at cache_shmlog.c:87 (
VSC_main->shm_cycles++;)

Solaris version is:  5.10 Generic_120011-14 sun4v sparc SUNW,Sun-Fire-T2000
Varnish is compiled with gcc version 3.4.6
