            Bug ID: 98690
           Summary: unexpected "'removed_return.213' may be used
                    uninitialized in this function" causes crash
           Product: gcc
           Version: 10.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org

Created attachment 49968

code exhibiting bug

When compiling the attached code I get:

error: 'removed_return.213' may be used uninitialized in this function
[-Werror=maybe-uninitialized]

and the error points to the 'endl' in that line.

If I downgrade the "maybe-uninitialized" to just a warning then it compiles but
the code crashes on that line.

The command line is:

  g++ -fnon-call-exceptions -Wmaybe-uninitialized -O2 gcc10bug.cpp
gcc10bug_main.cpp

If I remove -fnon-call-exceptions the the code compiles and runs as expected.
The code also runs just fine with GCC 9.1.0.
