Bug ID: 47306
Summary: Segfault compiling omp taskloop nested inside omp task
Product: OpenMP
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Clang Compiler Support
Assignee: unassignedclangbugs at nondot.org
Reporter: schuchart at hlrs.de
CC: llvm-bugs at lists.llvm.org

Preprocessed sources of the reproducer
I am trying to compile a simple reproducer for another issue that contains a
taskloop construct inside an omp task construct. Clang
(llvmorg-12-init-4019-g2501e911a5) aborts with the error below. I am attaching
the preprocessed sources, compiled with:
$ clang++ -O2 -fopenmp test_nested_taskloop.cc -o test_nested_taskloop.cc
The error (some paths replaced by me):
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash
backtrace, preprocessed source, and associated run script.
