Sorry to bother you, but I am too stupid to understand how to use bugzilla.
So I send this bug report via the way of last resort.
The following does not link.
module bla
logical, save :: blub= .true.
logical :: pa
equivalence (blub, pa)
end module
program po
use bla, only : pa
write (*,*) pa
end program po
! > gfortran Equivalence-Bug.f90 -static
! /tmp/UserName/ccOoVp3X.o: In function `MAIN__':
! Equivalence-Bug.f90:(.text+0x61): undefined reference to `__bla__pa'
! collect2: ld returned 1 exit status
Cordially,
Warner
