Bug ID: 52117
Summary: [OpenMP 5.0] Crash caused by target region inside of
task construct with affinity clause
Product: OpenMP
Version: unspecified
Hardware: Other
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Clang Compiler Support
Assignee: unassignedclangbugs at nondot.org
Reporter: thuber at udel.edu

C program that reproduces the crash
Overview: Test crashes and produces segmentation fault with Clang 14 when
compiling a test that utilizes a target region inside of a task construct that
specifies the affinity clause.
Steps to Reproduce:
Use 'clang -lm -O3 -fopenmp -fopenmp-targets=nvptx64 reproducer.c' to compile
the attached program.
Actual Results:
Program crashes.
Expected Results:
Test 'passes' with errors variable equal to 0.
