Comment (by luc):

 I've identified when log_ptr is incorrect.

 {{{
 *pp = (void*)(uintptr_t)vsl->log_ptr; /* Loose volatile */
 vsl->log_ptr = VSL_NEXT(vsl->log_ptr);
 }}}

 An assert just after the block trigger the error: ''Assert error in
 vsl_nextlog(), vsl.c line 202''
 {{{
 *pp = (void*)(uintptr_t)vsl->log_ptr; /* Loose volatile */
 vsl->log_ptr = VSL_NEXT(vsl->log_ptr);
 assert(vsl->log_ptr < vsl->log_end);
 }}}
