As pointed out in the glibc bug[1], there's a kernel bug preventing unwinding due to an incorrect pointer being copied to userspace. A 1-line patch[2] has been committed to Linus's tree to fix this.
I investigated, and this only affects 4.15, so we only need this applied to bionic.

SRU Justification
Impact: On s390, an incorrect pointer being copied from the kernel to userspace breaks stack unwinding.
Fix: One-line change from upstream. Only needed for 4.15+.
Test Case: The glibc testsuite contains test cases, which currently fail with 4.15.
Regression Potential: Minimal as this is a small, obvious bug fix for as single architecture.
