            Bug ID: 88161
           Summary: libbacktrace cannot find executable file on
                    i586-*-freebsd
           Product: gcc
           Version: 9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libbacktrace
          Assignee: unassigned at gcc dot gnu.org
          Reporter: kargl at gcc dot gnu.org
                CC: ian at gcc dot gnu.org
  Target Milestone: ---

File a.f90 contains code that should cause gfortran to emit a
backtrace.  If I execute the actual compiler f951, libbacktrace
still fails.

% gfortran9 -c a.f90
libbacktrace could not find executable to open
