Re: gcc7/libgcc7 problems
Iain has asked for a minimal reproducer and a bisected commit that generated the error. Then it's worth opening the bug report. I tried a few different iostream with locale test files, but so far couldn't repro the error.

I fail to see why it would be complicated at all. The 7.5 update was minimal. https://github.com/macports/macports-ports/commit/dd197967ac1c9fb9b489ee4e347a2f5a859f9839#diff-a55581cf79dd67b30d377c9affc5fce6 Reverting back to 7.4 only for old OSes would be trivial to do. In fact, it would make things easier for you, as then you would not have to reinstate the patch removed in. https://github.com/macports/macports-ports/commit/dcefaea1eca247c8ed6e8feb6d982598446c172e#diff-a55581cf79dd67b30d377c9affc5fce6 As you would still use 7.5 on the platforms needing that patch. 7.5 is the legacy 7.x release. Regardless of whether or not users should be using a newer major version, we should not force users back to 7.4 on the majority of systems that can perfectly happily use 7.5 > > Ah well, maybe Iain will fix it.

gcc7/libgcc7 problems
If you do decide to do this please only do it where needed, i.e. on i386 or 10.5 PPC. Newer systems that work fine with 7.5 should stay on that version. Hmm. May be too complicated to do that. gcc7 installs nothing much useful on newer systems anyway. Ah well, maybe Iain will fix it. My systems are fine, after rolling back to libgcc7 7.4.x When you see tickets, just tell people to roll back for the next few months until this gets properly sorted out, if it ever does. K

gcc7/libgcc7 problems
We're having troubles with the recent gcc7 upgrade to 7.5.0 on i386 (bootstrapping with non-system assembler) and on 10.5 PPC (bus errors in memory handling, possibly related to locale support, maybe some other thing TBA). We may have to bump epoch and roll back to last 7.4.x unless we can get this sorted out soon, as tickets are starting up... Ken
