[Bug tree-optimization/40999] New: ICE in extract_component, at tree-complex.c:625

[rguenth at gcc dot gnu dot org]

We ICE there because we don't fold CONST_DECLs substituted by inlining.

./f951 -quiet -O2 -finline-functions zheev.min7.f -fwhole-file
zheev.min7.f: In function 'zlarfg':
zheev.min7.f:1:0: internal compiler error: in extract_component, at
tree-complex.c:625

      SUBROUTINE ZLARFG( ALPHA )
        ALPHA = ZLADIV( DCMPLX( 1.0D+0 ) )
      END
      COMPLEX*16 FUNCTION ZLADIV( X )
        COMPLEX*16         X
        CALL DLADIV( DBLE( X ), DIMAG( X ) )
      END

reduced from two SPEC 2006 testcases that ICE this way on the LTO branch.
