Ian Lance Taylor <ian at airs dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ian at airs dot com --- Comment #4 from Ian Lance Taylor <ian at airs dot com> --- Note that zlib is only used for the test programs, not for libbacktrace itself. Are you sure that libgfortran is picking up a dependency on zlib? If that is coming from libbacktrace, then something else is going wrong.
