Description
I have symlinked network directory:
C:\>dir
Volume in drive C has no label.
Volume Serial Number is XXXX-XXXX
Directory of C:\
...
15. 03. 2017 17:55 <SYMLINKD> SHARED \\VBOXSRV\SHARED
...
0 File(s) 0 bytes
17 Dir(s) 1 126 232 064 bytes free
When application is executed from this symlinked directory, then Qt application is crashing (see error in subject).
I tried to find the reason using Process Monitor (from SysInternals) and found wrong path translation.
Network directory: \\VBOXSRV\SHARED\
Symlinked directory: C:\SHARED
Application directory: C:\SHARED\HHFARMA_DEPLOY\
Wrong translations (find C:\UNC strings in the log below):

Result is that some DLLs (e.g. qwindows.dll) are not found and application ends with error.
Note that some DLLs are loaded correctly.
