Bug ID: 48607
Summary: Crash during clang openmp codegen for firstprivate()
of `float _Complex`, only when debug info is present
Product: OpenMP
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Clang Compiler Support
Assignee: unassignedclangbugs at nondot.org
Reporter: lebedev.ri at gmail.com
CC: llvm-bugs at lists.llvm.org
I'm not sure if this is a (recent) regression or not.
$ cat input.c
a() {
float _Complex b;
#pragma omp parallel firstprivate(b)
;
}
