Description Daniel Berrangé 2013-09-13 12:45:39 UTC 
spice-gtk copied the gtk-vnc coroutine_ucontext.c so suffers from this same flaw

+++ This bug was initially created as a clone of Bug #1007837 +++

Description of problem:
The ucontext coroutine implementation mmap()s 16 MB of memory for the coroutine stack, but fails to ever unmap it. This causes the stack to leak for each coroutine started

Version-Release number of selected component (if applicable):
gtk-vnc-0.5.2-2.el7

How reproducible:
Always


Steps to Reproduce:
1. Run demo program in https://bugzilla.gnome.org/show_bug.cgi?id=705827 it will consume memory until exhausted, then crash.
2.
3.
