Compiling a program using DMD on macOS Catalina (10.15) beta 2 gives the
following error:
dyld: lazy symbol binding failed: Symbol not found: _dyld_enumerate_tlv_storage
Referenced from: ~/.dvm/compilers/dmd-2.086.0/osx/bin/dmd
Expected in: /usr/lib/libSystem.B.dylib

Abort trap: 6
"dyld_enumerate_tlv_storage" was a private symbol part of dyld (the dynamic
loader). It is used to get the memory locations of all the thread local storage
variables to register them as roots with the garbage collector. This symbol
doesn't seem to exist anymore on macOS Catalina.
This issue will apply to LDC as well.
