Bug ID: 23132
Summary: Encountered an `unhandled type tag` error on malformed
`print` statement
Product: lldb
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: All Bugs

Classification: Unclassified
Was testing out `lldb` in stepping through a simple mean function, and stumbled
into this:
Breakpoint 2: where = sourceCpp_57725.so`Rcpp::sugar::Mean<14, true,
Rcpp::Vector<14, Rcpp::PreserveStorage> >::get() const + 351 at mean.h:46,
address = 0x000000010cf7e79f
(lldb) c

sourceCpp_57725.so`Rcpp::sugar::Mean<14, true, Rcpp::Vector<14,
Rcpp::PreserveStorage> >::get(this=<unavailable>) const + 351 at mean.h:46,
queue = 'com.apple.main-thread', stop reason = breakpoint 2.1

43 for (int i = 0; i < n; i++) {
44 t += input[i] - s;
45 }
-> 46 s += t/n;
47 }
48 return (double)s ;
49 }
(lldb) print s

error: warning: Stopped in a C++ method, but 'this' isn't available; pretending

This is with git commit `1fe2076d4c88fcf374a1ce8f5486c340cb61a304`; `lldb` was
built from sources using
xcodebuild -configuration Release -target lldb-tool
Thanks,
Kevin
