rtmutex deadlock and memory corruption when running gcc testsuite in next-20260303

[Bert Karwatzki <spasswolf@web.de>]

I tried building gcc-14 from the debian repositories (fetched via apt-get 
source gcc-14) on my new and shiny zen5 machine (Cpu: "AMD Ryzen 9 9950X 
16-Core Processor) running debian stable/trixie and linux-next-20260303 
(PREEMPT_RT=y) with the following command:

$ time dpkg-buildpackage --no-sign -B -nc

after about ~1.45h, during the testsuite, the following error happens:

After this error the system does not work properly anymore (htop and ps
don't work anymore, xfce still works, evolution refuses to start and shutting down also hangs) 

I recently successfully compiled gcc-14 from debian on linux-6.18.13, so I'm going to bisect this.
Depending on wether I can single out the offending test this could take a while so I'm
reporting this before the bisection is finished.
