[Bug 1851948] [NEW] pthread_detach memrery leak

[qinpan1003]

Public bug reported:

Ubuntu:   Linux ubuntu 5.0.0-29-generic #31~18.04.1
glibc:    GNU C Library (Ubuntu GLIBC 2.27-3ubuntu1) stable release version 2.27.
pthread:  NPTL 2.27

When I use pthread_detach, I find that the system does not recycle
resources, and the program consumes more and more memory, which is
finally killed by the system.

** Affects: glibc (Ubuntu)
     Importance: Undecided
         Status: New
