System Information

• Operating system: Aros
• Processor architecture: x86_64
• Compiler version: trunk

Steps to reproduce

Apply patch above and compile rtl and packages for x86_64-aros target, using:

 make rtl packages CROSSOPT="-n -gl" OS_TARGET=aros CPU_TARGET=x86_64

This bug report clearly shows that acceptable unit code which depend mutually on each other and contain inline code can lead to a dead-lock in the current ctask unit.
