Fail read calls after exception. (same as #12590) #12593
Fail read calls after exception. (same as #12590) #12593
Conversation
If a read call was performed after XrdFile threw an exception, it is possible there are no active sources. However, not all paths check for the case of zero sources and may use-after-free the last source. This caused a deadlock at the Tier-0.
