This means we should likely fix posix_spawn in glibc to support this deviation from the kernel interface. Other Linux emulations have exactly the same problem. For emulating 32-bit targets, we have a broken readdir/telldir/seekdir implementation in glibc on 64 bit host kernels because we try to use d_ino directly, which is 64 bit and does not fit into the long value that POSIX requires. A kernel patch with a new interface has been posted which would work around this has been proposed, but it is not going anywhere. The second issue also affects full-system virtualization if p9fs (not sure what the right name is, it's the older pass-through file system) is used. But it's specific to 32 bit, so maybe not that important after all.
