-Attached is a test case source code extracted from libgomp test suite.
-
-Note that it is a multi-threaded and requires 5 or more threads to fail. Number of launched threads is controlled by OMP_NUM_THREADS evironment variable, defaulting to number of hardware threads. Changing constants in the test case makes it fail with different numbers of threads.
-
-I will attach statically linked riscv64 binary executable if size limits permit.
-
-
-
-
-
-I noticed that this crash is not target specific and it is possible to reproduce it using qemu-x86_64 with the testcase above
-
-The following patch should fix that: http://lists.nongnu.org/archive/html/qemu-devel/2018-03/msg07437.html
-
-Should be fixed by 73a988d957b9142e0 (which is the patch jcmvbkbc mentions in comment #4), now in master and will be in 2.12.0.
