Bug ID: 100744
Summary: Undefined symbol __gcov_flush when building with
-fprofile-arcs
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: gcov-profile
Assignee: unassigned at gcc dot gnu.org
Reporter: raffael at casagrande dot ch
CC: marxin at gcc dot gnu.org
Target Milestone: ---
Trying to link the following simple program with `-fprofile-arcs` fails:
------------------
extern "C" void __gcov_flush();
int main() {
__gcov_flush();
}
------------------
Command line: `g++ source.cc -fprofile-arcs`
This used to work with gcc-10.3. It seems to be a regression of gcc-11.1/trunk?
