+++ This bug was initially created as a clone of Bug #1030245 +++

Looks like adb logcat will implicitly add a new line if it's missing from the end but this doesn't happen on the desktop or the profiler.

This feels too clunky to me. If getline() doesn't tack on the \n then we should just do that in the printf_stderr call. It sounded like the problem then is that we get a blank line at the end of the dump, which we should be able to strip out like so:

     while (!ss.eof()) {
       ss.getline(line, sizeof(line));
-      printf_stderr("%s", line);
+      if (!ss.eof() || strlen(line) > 0) {
+        printf_stderr("%s\n", line);
+      }
       if (ss.fail()) {
         // line was too long, skip to next newline
         ss.clear();
         ss.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
       }
     }

Presumably you want to keep the fprintf_stderr(gfxUtils::sDumpPaintFile...
