 Greetings:

 I am currently unable to use GDB 8.0.1 on macOS High Sierra. For those
 curious, the message I get "warning: unhandled dyld version (15)" is
 occurring because gdb 8.0.1 doesn't include commit 4bbd4ef (1), which
 updates the maximum version of dyld that gdb says it can handle (2). Thank
 you for your help with this.

 gdb/commit/4bbd4ef219c5b4c7d437618ba8937af86dd1032e 4bbd4ef]

 Kind regards,
 Anthony
