          Issue ID: 22542
           Summary: Explicitly cast backtrace results to int
           Product: D
           Version: D2
          Hardware: All

Hello --

I would like to explicitly cast the result on backtrace on Posix (non-Apple)
systems. For Linux, this app a no-op. However, on OpenBSD (and others?)
backtrace returns a size_t.

Note this is what LDC does:
https://github.com/ldc-developers/druntime/blob/ldc/src/core/runtime.d#L789

I need this in order to switch the OpenBSD backtrace implementation from a
handrolled version to the version built into OpenBSD. Both Linux and macOS use
their own built in versions.
