Yes.
This is an expected result of the jmpbuf extension. I've tried to minimize the
effect by versioning all the accessor functions but symbol versioning is not
available for data structures. In the end there is just one header file
defining the structure. Code which uses the old header file is not compatible
with code using the new header file in case jmpbufs are transferred between the
two.
This happened in the past already. E.g. for Power with the introduction of
Altivec or with the long double 64->128 bit extension.
