------- Comment #14 from Chris Vine 2008-06-19 10:17 UTC -------
Even better, a third solution would be to be able to pass a custom container
object to the sigc::trackable constructor as a constructor argument, or to have
the container type as a template type (as with std::queue) - it would then be
possible to pass in a thread-safe container (I would choose std::set rather
than std::list anyway).
That would avoid any dependency issues.

glibmm | main loop | Ver: 2.16.x
Summary: destroy() deletes its Glib::Source instance
Product: glibmm
Version: 2.16.x
Platform: Other
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: main loop
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
QAContact: [EMAIL PROTECTED]
GNOME version: 2.21/2.22
GNOME milestone: Unspecified
In the glib C API, g_source_destroy() removes a source from its attached
context and marks it as destroyed; that's also the behavior documented for
Glib::Source::destroy(). The glibmm implementation, however, ends up deleting
the Glib::Source instance, not merely marking it as destroyed.
The same instance is later deleted again by its Glib::RefPtr, so calling
destroy() can easily and unavoidably cause heap corruption. This issue makes it
effectively impossible to safely detach a source from a context in glibmm.
I've attached a small example involving a derived source. The same issue is
also present for the standard event sources (Glib::TimeoutSource and friends).

gtkmm | build | Ver: 2.8.x
------- Comment #2 from Eduardo Bacchi Kienetz 2008-06-20 02:47 UTC -------
(In reply to comment #1)
> What version of GTK+ are you using?
# ls /var/log/packages/gtk+*
# gtk+-1.2.10-i486-4 gtk+2-2.12.9-i486-1
These are the gtk+* I have installed (default from slackware), now, which one
gtkmm is getting to use I don't know. How could I find out?
Anyway... sorry, I didn't see there are newer versions. I'll try compiling
2.10.11 to check if the error persists and keep moving to newer ones if it
still happens.

You have GTK+ 2.12, so I suggest that you use gtkmm 2.12, not GTK+ 2.8. This
error is probably due to new deprecations in GTK+.
