Description Diego Elio Pettenò (RETIRED) gentoo-dev

/usr/share/crossdev/include/site/linux reports

glib_cv_sizeof_gmutex=40

but the variable should rather be 24 at least on i386; the size it reports is the size of pthread_mutex_t which is arch-dependent.

The problem is that since this is overridden when crossdev is installed, you have a nastily broken glib that, among other things, would make VMware crash (as reported by PaX Team).

The value should probably be moved to x86_64-linux-gnu, rather than linux only, and separated for other platforms.

@GNOME: you _might_ want to add a blocker on the current version of crossdev for glib, just to be on the safe side.

Fixed this on the crossdev git repository, Mike can you please take care of the release?

Comment 2 Johan Ymerson 2011-06-10 07:01:40 UTC

Why is this bug marked resolved?
It is _not_ resolved. There is no new ebuild in portage.
A new, clean, install of Gentoo with crossdev still get this problem.

For completeness, it was fixed in:
