Re: [libvirt] [PATCH] build: avoid type-punning compiler warning

2011/7/27 Eric Blake <eblake@redhat.com>:

On RHEL 5, with gcc 4.1.2:

rpc/virnetsaslcontext.c: In function 'virNetSASLSessionUpdateBufSize': rpc/virnetsaslcontext.c:396: warning: dereferncing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]

* src/rpc/virnetsaslcontext.c (virNetSASLSessionUpdateBufSize): Use a union to work around gcc warning. ---  src/rpc/virnetsaslcontext.c |   11 +++++++----  1 files changed, 7 insertions(+), 4 deletions(-)
