I compiled bash statically by making the following changes:

diff --git a/meta/recipes-extended/bash/bash.inc b/meta/recipes-extended/bash/bash.inc
index 3684191..071d79e 100644

 export CC_FOR_BUILD = "${BUILD_CC}"
 
 ALTERNATIVE_${PN} = "sh"

That seems to be working!

I get a bash shell prompt with no issues. 

Not sure at this moment, if it was the updates to gcc-4.7.2 that fixed the problem or if there is still a problem with the init scripts.

I'll try to switch back to a non-static bash, and try booting the core-image-minimal filesystem once again.

Best regards,
