Bug ID: 18595
Summary: ctan, ctanh missing underflows
Product: glibc
Version: 2.21
Status: NEW
Severity: normal
Priority: P2
Component: math
Assignee: unassigned at sourceware dot org

Target Milestone: ---
ctan and ctanh fail to raise underflow exceptions for some cases that should
underflow, e.g. for float on x86_64:
Failure: Real part of: ctan (-0x8p-152 + +0 i): Exception "Underflow" not set
Failure: Real part of: ctanh (+0 - 0x8p-152 i): Exception "Underflow" not set
