process just hangs and won't proceed with

checking for stack setup via sigaltstack...

can you please paste a bit before the hang?
Also look at the process listing and take a guess whats blocking here.
Using lsof may help to identify what files it has open.
Please also attach the config.log just incase I need it (normally in the
toplevel of /var/tmp/portage/pth-2.0.6/workdir/pth-2.0.6).

I've got exactly the same problem with version dev-libs/pth-1.4.0.
It stops here:

pth-2.0.6-sigstack.patch

I know this is a stupid fix for the problem... but I also checked newer version
2.0.7, and it is the same.
For some this step causes infinite loop, and for some segmentation failure.

So I've made this step always fail, so the size will be guessed.

patches added. Thanks Miro and Alon.

So is this fix going to make it into the portage tree, or do I need to patch it
myself?

This bug is marked as RESOLVED FIXED, so it is fixed in portage.
If you have some other issue, please open a new bug, and specify the details.

I am getting the exact same outcome with 2.0.7-r1
