Solaris: vasprint fix for %llu crash
vasprint now inturn call gf_vasprintf, which calls vsnprintf. vsnprintf allocates buffer of required size, and hence prevents the sigsegv seen in vasprintf w.r.t %llu Signed-off-by: shishir gowda <shishirng@gluster.com> Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 1058 (vasprintf dumps core when %llu is involved) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=1058
