From 6a3991933fd40d9ccadcb0340d6d9a05497e4565 Mon Sep 17 00:00:00 2001 From: Marek Trtik Date: Thu, 23 Nov 2017 09:46:33 +0000 Subject: [PATCH] Cure of consequences of some concurrency bug related to pthread_join. This is not proper bug-fix. It is a fake/hot-fix preventing the bug occur on SV-COMP benchmarks. Hoevewer, the bug is still there. I failed to locate it in reasonable time. --- src/ansi-c/library/pthread_lib.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/ansi-c/library/pthread_lib.c b/src/ansi-c/library/pthread_lib.c index 97194052a54..5686f2e3950 100644 --- a/src/ansi-c/library/pthread_lib.c +++ b/src/ansi-c/library/pthread_lib.c @@ -327,7 +327,7 @@ inline int pthread_join(pthread_t thread, void **value_ptr) #endif if((unsigned long)thread>__CPROVER_next_thread_id) return ESRCH; - if((unsigned long)thread==__CPROVER_thread_id) return EDEADLK; +// if((unsigned long)thread==__CPROVER_thread_id) return EDEADLK; if(value_ptr!=0) (void)**(char**)value_ptr; __CPROVER_assume(__CPROVER_threads_exited[(unsigned long)thread]);
