See Issue: llvm/llvm-project#59007. Although this issue has been fixed in LLVM, the fix will not probably propagate to older versions of Ubuntu and GCC-13.1.
Starting with GLIBC version 2.34, the
dn_expand
function, previously found inlibresolv.so
, was moved tolibc.so
. This function is used internally by thegetaddrinfo()
system call.In our setup, we are using an Ubuntu 18 Docker image on a newer Ubuntu host. However, due to compatibility issues between newer libasan.so in GCC 13.1 and the older Ubuntu image, the linker does not link with
libresolv.so
. This results in crashes ingetaddrinfo()
.This problem does not occur on Ubuntu 22 and newer because GLIBC versions 2.34 and above include
dn_expand
inlibc.so
, eliminating the dependency onlibresolv.so
.We can bypass this problem by linking with "resolv" manually until we bump our base Linux image to Ubuntu 22.
