Unsure of exactly how to communicate this one, so posting here.
Compilation of https://github.com/dcarp/asynchronous. Using 'dub --verbose build' produces: dmd -lib -of.dub/build/library-debug-linux.posix-x86_64-dmd_2071-7450FEAE5605F646044C35441C27D67E/libasynchronous.a -debug -g -w -version=CryptoSafe - version=Have_asynchronous -version=Have_libasync -version=Have_memutils -Isrc/ -I../../../../.dub/packages/libasync-0.7.9/libasync/source/ - I../../../../.dub/packages/memutils-0.4.6/memutils/source/ src/asynchronous/events.d src/asynchronous/futures.d src/asynchronous/libasync/events.d src/asynchronous/locks.d src/asynchronous/package.d src/asynchronous/protocols.d src/asynchronous/queues.d src/asynchronous/streams.d src/asynchronous/tasks.d src/asynchronous/transports.d src/asynchronous/types.d -vcolumns Enhanced memory security is enabled.

However, if I do not use dub to compile the code, and compile into individual object files, then for the following file: /usr/bin/dmd -ofbuild/events.d.o -debug -g -w -version=CryptoSafe -version=Have_asynchronous -version=Have_libasync -version=Have_memutils -Isrc - I../../../../.dub/packages/memutils-0.4.6/memutils/source/ -I../../../../.dub/packages/libasync-0.7.9/libasync/source/ -c src/asynchronous/libasync/events.d for any dmd >2.068 causes the following error: dmd: glue.c:809: void FuncDeclaration_toObjFile(FuncDeclaration*, bool): Assertion `fd->semanticRun == PASSsemantic3done' failed. Aborted However, it works find for dmd.2.068. Any ideas?
