AIUI the result of =E2=80=98ftell=E2=80=99 is used in only one place, while= =E2=80=98port-line=E2=80=99 and =E2=80=98port-column=E2=80=99 are used in other places. The latter see= ms more appropriate to me when it comes to tracking source location. How is the result of =E2=80=98ftell=E2=80=99 used by callers of =E2=80=98re= ad-lily-expression=E2=80=99? > I=C2=A0have more than enough crashes and obscure errors to contend with as > it stands, Could you open a separate bug with the backtrace of such crashes, if you think it may be Guile=E2=80=99s fault? Thanks, Ludo=E2=80=99.
