I found the source of the problem. Due to other constraints, we are forced to LD_PRELOAD libGL. This in turn preloads libnvidia-tls, which apparently messes up something with the glibc tls support. Removing the libGL preloading fixes the issue, although it introduces another, but I'll figure something out. Thanks for the help! -- Stefano Borini QuantumWise A/S
