================
Comment at: lldb/source/Core/IOHandlerCursesGUI.cpp:438-450
+    va_list args;
+    va_start(args, format);
+    int size = vsnprintf(nullptr, 0, format, args);
+    va_end(args);
+    if (size <= 0)
+      return;
+    ++size; // for \0
----------------
Use StreamString?:
```
#include "lldb/Utility/StreamString.h"
void PrintfTruncated(int right_pad, const char *format, ...)
      __attribute__((format(printf, 3, 4))) {
  va_list args;
  va_start(args, format);
  StreamString strm;
  strm.PrintfVarArg(format, args);
  va_end(args);
  PutCStringTruncated(right_pad, strm.GetData());
}
```
