Bug ID: 21517
Summary: struct sigaltstack namespace
Product: glibc
Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: jsm28 at gcc dot gnu.org
CC: drepper.fsp at gmail dot com
Target Milestone: ---
glibc defines the stack_t type with the tag struct sigaltstack. This is not
permitted by POSIX; sigaltstack is only reserved with file scope in the
namespace of ordinary identifiers, not the tag namespace, and in the case where
stack_t is obtained from ucontext.h rather than signal.h, it's not reserved
with file scope at all.
