# This tests a bug where we would incorrectly parse the size of an array if that
# size happened to match an existing DIE offset. This happened because we
# misinterpreted that value as a reference to a DIE specifying the VLA size even
# though the form was a data form (as it should be).
# REQUIRES: lld
# RUN: llvm-mc -triple x86_64-pc-linux %s -filetype=obj > %t.o
# RUN: ld.lld %t.o -o %t
# RUN: lldb-test symbols %t | FileCheck %s
# CHECK: Variable{0x0000001e}, name = "X"
# CHECK-SAME: type = {0000000000000033} 0x{{[0-9A-F]*}} (char[56])
# Generated from "char X[47];"
# The array size was modified by hand.
