Public bug reported:

In Ubuntu 20.04.1 (LTS) the ldc compiler (1:1.20.1-1) behaves
differently compared to the same version of the LLVM D compiler
installed from dlang.org.

We found the bug investigating a segfault in the OneDrive Client for Linux. 
Onedrive compiled with the Ubuntu ldc package segfaults when ^C is issued 
during operation.
The expected behaviour is that the application does not sefault. If onedrive is 
compiled using the DMD compiler or ldc compiler installed via 
dlang.org/install.sh (also version 1.20.1), the application does not segfault. 
So the Ubuntu ldc package behaves differently and seems to cause the issue.
