The bridge helper program is invoked directly from QEMU when it needs to attach to a network bridge. As such, it is subject to the environment of QEMU itself. Specifically, if bridging is enabled with direct rendering acceleration, QEMU is run with an LD_PRELOAD that attempts to preload several uninative libraries; however /bin/sh doesn't use the uninative loader which means it can fail to start with an error like: /bin/sh: symbol lookup error: sysroots-uninative/x86_64-linux/lib/librt.so.1: undefined symbol: __libc_unwind_link_get, version GLIBC_PRIVATE Converting the helper program to a C program resolves this problem because it will now use the uninative loader so the preload doesn't cause errors.
