I see this error during bootstrap:

../../gcc/gcc/fortran/resolve.c:12359:19: error: large integer implicitly truncated to unsigned type

The value -1 is assigned to the unsigned bitfield "resolve" in a
struct gfc_namespace.
Comment 1 Jorn Wolfgang Rennecke 2010-01-20 07:49:04 UTC 
Actually, I see now that the patch for PR40011 was all right at the time,
it was the patch for PR39626 which introduced PR42812.
