Description Vidya Praveen 2015-05-21 12:57:41 UTC 
I'm seeing this while building arm-none-linux-gnueabi/gnueabihf at the stage of building libstdc++

[...]arm-none-linux-gnueabi/libc/usr/include/bits/types.h:134:30: internal compiler error: verify_type failed

This looks similar to bug 66214 but not sure if it's the same. Attaching a preprocessed file that reproduces this with g++ -g -O0

Confirmed.
Comment 3 Vidya Praveen 2015-05-21 17:45:02 UTC

Comment 4 ktkachov 2015-05-22 09:33:16 UTC 
I'm seeing this as well (as it is blocking the arm-none-linux-gnueabihf build)
