Description:
While doing C++ debugging with QtCreator I am unable to view contents of a std::string in the debug pane.
I tried with GCC+GDB and Clang+lldb, with the same result.
gcc-9.1.0_3
gdb-8.3_1
clang-8.0.0_7
lldb-8.0.0_7
I'm not sure if these packages are related to the issue at all. Nor am I certain this is a bug upstream to QtCreator. I searched using Google and it didn't seem that any other users experiences this.
It could be worth noting that I am using Void Linux at work as well, with QtCreator, GCC and GDB; basically the same environment I use here at home. So, at work, I have none of these issues, and I have not updated that system since August 1st or 2nd.
My system here at home I updated by latest today. However my previous update, about 1-2 weeks ago, I am sure I also received GCC 9.
After the update few weeks back, on my home computer, I launched a debug of one of my pet-projects (no recompiling!) and it ran fine, I could view std::string and do my usual things. I did some source-modifications and re-compiled, and right after that, std::string was not accessible; on all my projects, not even on a simple test-source with a main() and some function calls with a little deeper callstack.

### System
* xuname:  
  Void 4.19.69_1 x86_64 GenuineIntel uptodate rrrrmmnFFFFFF
* package: 
  qtcreator-4.9.2_3

### Expected behavior
std::string is visible in debug pane

### Actual behavior
std::string shows as "not accessible"

### Steps to reproduce the behavior
Create a simple test C++ application using a std::string and try reading its output via a breakpoint. Some times it might show, but in that case, it seems that it might also fail under a little deeper call-stack than just main(). Depth of my call-stack is 5, but is also failing higher up.

Comment:
I finally got some time to investigate further. It seems it must be a problem upstream. I tested this on the Solus distribution as well, with same results. They also have similar package versions as here in Void, GCC 9, Qt Creator 4.9.2.

I'm not sure if these packages are related to the issue at all. Nor am I certain this is a bug upstream to QtCreator. I searched using Google and it didn't seem that many other users experiences this, at least from the past months.
