From b3be1651f4a45660b447881f7c61c03a1b24302a Mon Sep 17 00:00:00 2001 From: Keith Whitwell Date: Fri, 13 Mar 2009 15:49:49 +0000 Subject: mesa/st: add check for null front renderbuffer Not sure if this indicates a problem elsewhere, but without this check trivial/tri-fbo.c segfaults on resize. With the patch, it renders correctly. --- src/mesa/state_tracker/st_cb_flush.c | 21 ++++++++++++--------- 1 file changed, 12 insertions(+), 9 deletions(-) (limited to 'src/mesa') diff --git a/src/mesa/state_tracker/st_cb_flush.c b/src/mesa/state_tracker/st_cb_flush.c index 4fdb6730879..7d7d3823c99 100644 --- a/src/mesa/state_tracker/st_cb_flush.c +++ b/src/mesa/state_tracker/st_cb_flush.c @@ -63,16 +63,19 @@ display_front_buffer(struct st_context *st) GLframebuffer *fb = st->ctx->DrawBuffer; struct st_renderbuffer *strb = st_renderbuffer(fb->Attachment[BUFFER_FRONT_LEFT].Renderbuffer); - struct pipe_surface *front_surf = strb->surface; - /* Hook for copying "fake" frontbuffer if necessary: - */ - st->pipe->screen->flush_frontbuffer( st->pipe->screen, front_surf, - st->pipe->priv ); - - /* - st->frontbuffer_status = FRONT_STATUS_UNDEFINED; - */ + if (strb) { + struct pipe_surface *front_surf = strb->surface; + + /* Hook for copying "fake" frontbuffer if necessary: + */ + st->pipe->screen->flush_frontbuffer( st->pipe->screen, front_surf, + st->pipe->priv ); + + /* + st->frontbuffer_status = FRONT_STATUS_UNDEFINED; + */ + } } -- cgit v1.2.3
