            Bug ID: 15765
           Summary: sem_open is wrongly a cancellation point
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org

test demonstrating the bug

sem_open uses functions which are cancellation points and makes no effort to
block cancellation. Even if it were permitted to be cancellable, its current
usage of these functions would lead to resource-leak race conditions. Test
program demonstrating the bug is attached.
