Description NHO 2025-01-28 17:53:12 UTC 
After configuring lto according to wiki, started to rebuild the world
ast.hpp:127:9: error: virtual table of type 'struct Expression' violates one definition rule [-Werror=odr]
  127 |   class Expression : public AST_Node {
      |         ^
ast.hpp:127:9: note: the conflicting type defined in another translation unit
  127 |   class Expression : public AST_Node {
      |         ^
<built-in>: note: virtual method '__cxa_pure_virtual'
ast.hpp:155:13: note: ought to match virtual method '__conv_op ' but does not
  155 |     virtual operator bool() { return true; }
      |             ^
lto1: some warnings being treated as errors


I think it's double include.

Reproducible: Always

Reported upstream in https://github.com/sass/libsass/issues/3193
Comment 6 NHO 2025-01-31 11:06:09 UTC 
Upstream recommends to build without "-fno-semantic-interposition"

After changing flags, package builds with -flto.
