Description Saul Wold 2014-05-06 17:22:39 UTC

This error is showing itself with the newer 4.9 version of GCC, which has recently been included, but not yet fully enabled for 1.7.

To reproduce this, you will need to change the GCCVERSION to 4.9 in the meta/conf/distro/include/tcmode-default.inc as follows:

-GCCVERSION ?= "4.8%"
+GCCVERSION ?= "4.9%"

Then you can build libgcc

this is changing the ABI. I think we can wait for real fix.
