Bug ID: 28769
Summary: Coverage data includes call to __cxx_global_array_dtor
Product: clang
Version: 3.9
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: unassignedclangb...@nondot.org
Reporter: llvm.flamef...@spamgourmet.com
CC: dgre...@apple.com, llvm-bugs@lists.llvm.org
Classification: Unclassified

GCOV file
I was using clang++ with the --coverage flag to generate coverage data on a
larger project (https://github.com/Return-To-The-Roots/s25client)
However I see an completely unexpected call to "__cxx_global_array_dtor" in the
gcno file which should not be there and leads to false positives. The line I've
seen this is this one:
https://github.com/Return-To-The-Roots/s25client/blob/14796d1cb7423a87f9698001db650fa6262ae4ee/src/ingameWindows/iwPostWindow.cpp#L69
A line that is almost the same as the surrounding ones, but the only one that
got that call attributed.
I was not able to create a mini-example with this behaviour as clang coverage
works in almost all other cases, especially trivial ones.
I attach the raw gcov file (llvm-cov gcov <gcda file> --dump), just search for
"__cxx_global_array_dtor"
