Bug ID: 50739
Summary: Race condition in regression test bug49334.cpp
Product: OpenMP
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Runtime Library
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
The regression test bug49334.cpp occasionally fails because of a race condition
in the asynchronous data movement. The test case was introduced in
https://reviews.llvm.org/D97329 to fix http://llvm.org/PR49334. PR49334 was a
null dereference not a race condition.
