So there is something strange happening. The context represented by the backtrace looks like the app binding to the POSIX skin, which must have happened way earlier automatically through the POSIX skin library constructor, before your app could even emit any Xenomai syscall. I initially thought of some mismatches between the POSIX skin and the UVM support related to some pSOS emulation use, but as there is no UVM/pSOS in the picture, I now understand that your environment is purely POSIX-based, so the latter cannot happen. IOW, something seems out of sync in your configuration.
