this bug has been reported upstream already in the beginning of April:
https://bugzilla.xamarin.com/show_bug.cgi?id=28679

I have added a comment there.

If I had access to a ppe64 machine, I would try to comment lines to find where exactly in https://github.com/mono/mono/blob/master/mcs/class/corlib/System/Console.cs#L140 the crash happens.

Or perhaps you can see something in that method SetupStreams() that is suspicious?

Hi Timotheus,

thanks for your infos, i will try and will report the results backs soon.

Than

there has been a comment on https://bugzilla.xamarin.com/show_bug.cgi?id=28679
Bill Seurer got it to work with prerelease GCC 5.0.1
he will post generic patches

i built mono-4.0.2 with his fix committed in GIT and still got the failfure

make[6]: mcs: Command not found
build/profiles/basic.make:93: recipe for target 'build/deps/basic-profile-check.exe' failed

Debug info from gdb:

This bug appears to have been reported against 'rawhide' during the Fedora 23 development cycle.
Changing version to '23'.

(As we did not run this process for some time, it could affect also pre-Fedora 23 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 23 End Of Life. Thank you.)

More information and reason for this action is here:
https://fedoraproject.org/wiki/BugZappers/HouseKeeping/Fedora23

Seems not to be completely fixed, some build, some don't
