>Description:
When compiling a C++ source file with the -fpack-struct flag, code is generated which segfaults when run. When creating
a similar C source file and using the same flag, there's no problem at all. The problem only occurs if there is a struct or class in the source file, if I remove the structs and compile with the flag, it runs just fine. I tried this to rule out the possibility that it had something to do with linking in default libraries or compiling files in <string> or <iostream> which are included in the source file.
