Package: libc6 Version: 2.28-10 Severity: important Dear Maintainer,
It seems ${PLATFORM} is wrongly expanded on x86_64 architectures with libc6 2.28. This leads to troubles while referencing libraries. This doesn't seem related to the usage of curly braces. You can find the reproductions steps below: $ arch x86_64 $ strace -ELD_PRELOAD='/sss/$PLATFORM/dddd' -s300 /bin/cat execve("/bin/cat", ["/bin/cat"], 0x5607e51d5490 /* 62 vars */) = 0 brk(NULL) = 0x560cc39d5000 readlink("/proc/self/exe", "/bin/cat", 4096) = 8 openat(AT_FDCWD, "/sss/haswell/dddd", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) $ strace -ELD_PRELOAD='/sss/${PLATFORM}/dddd' -s300 /bin/cat execve("/bin/cat", ["/bin/cat"], 0x563dc5b51490 /* 62 vars */) = 0 brk(NULL) = 0x55f8d420d000 readlink("/proc/self/exe", "/bin/cat", 4096) = 8 openat(AT_FDCWD, "/sss/haswell/dddd", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) Feel free to ask me any additionnal information.
