<div style="font-family:Arial;" class="">As noted by Ryan, GCC6 and prior use libgcc from GCC6. There is(are) ABI change(s) in libgcc from GCC6 to GCC7 (e.g., some different compatibility versions for libraries; some different symbols in libraries; some different version in filenames).

<div style="font-family:Arial;" class="">Yes, of course, i understand this. My point was really unless there is a reason not to the default libgcc port should be kept up to date with the latest stable release, which is as of now gcc7. I have no interest to work with a real devel release, so have no plans to update my libgcc port to libgcc-devel. <br class=""></div>
