clang++-11 crashed when compiling header files in qtbase
(clang++-12, clang++-14 don't have this problem)
Env: Ubuntu 20.04 x86_64
Command:
```
mkdir qt && cd qt
git clone --branch dev --depth 5000 git://code.qt.io/qt/qtbase.git
cd qtbase && git checkout 0804109d686e0a99ab0de0f1c70e3422183c6e98
cd .. && tar xvf include.tar.gz # see attachment
```
replace the path in include directory to absolute file path corresponding with your linux
e.g.
suppose your path to include directory is at /home/mypath/qt/
replace `/home/yangke/Program/Saryn/qt/qtbase/xxx/xxx.h` in *.h in extracted directory
with your own path: `/home/mypath/qt/qtbase/xxx/xxx.h`
for example,
```
cd ./include
find . -name *.h |xargs sed -i "s/yangke\/Program\/Saryn/mypath/g"
```
Reproduce crash!
```
clang++-11 -c ./qtbase/src/corelib/tools/qmap.h -I./include
```
```
...
some header not found error info
