I have uploaded a new version of cygport to the Cygwin distribution and the Fedora/EPEL Cygwin copr. This release reverts the split debuginfo compression commit due to a bug in binutils:
https://sourceware.org/bugzilla/show_bug.cgi?id=18087 I hope to restore this feature once this has been fixed upstream and we have a version of binutils with a backport of that fix. -- Yaakov
