            Bug ID: 87178
           Summary: Compilation failure when program contains multiple
                    variables allocated in particular section, and at
                    least one variable is C++17 "inline"
           Product: gcc
           Version: 9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jpmarath at gmail dot com
  Target Milestone: ---

This program fails to compile:
//--
inline __attribute__((section("foo"))) int xxx;
__attribute__((section("foo"))) int yyy;

int *p1 = &xxx;
int *p2 = &yyy;
//--


$g++ -std=c++17 -c m1.cpp

<source>:2:37: error: 'yyy' causes a section type conflict with 'xxx'

2 | __attribute__((section("foo"))) int yyy;

  |                                     ^~~

<source>:1:44: note: 'xxx' was declared here

1 | inline __attribute__((section("foo"))) int xxx;

  |                                            ^~~


The same program compile fine with clang (checked with clang 6.0)
