RESOLVED DUPLICATE of bug 45046

Description Alexey Bogdanov 2016-10-05 12:01:30 UTC
Calling Console.WriteLine() with some parameters crashes the app or gives strange output.

For examples:
Console.WriteLine("%7B%22src%22%3A%22");

In the empty (single view app) application gives this output:
"7            UTF8Stringrc23A2"

In our existing app it gives:
"7           autoreleaserc23A2"

In some cases similar input strings crash the app with this call stack:

It's critical bug, cause it can crash the app under some random circumstances.
