Please submit a full bug report,with preprocessed source if appropriate.

Why it does not fail during stage1 is interesting for me.

I got the same on hppa-linux:

See rev and commit info there.

Laurent, I don't seem to be able to reproduce your PA problem
from a cross-compile.  Please attach a preprocessed file that
exhibits the problem.

Likewise, Andrew, I'll need a preprocessed file.

Assuming something that doesn't show up w/ stage1 can even
be reproduced via cross-compiler.  Failing that, give me as
much information as you can about how the CFA variable changes
over the compilation of this function.

A bootstrap on hppa-linux-gnu works for me with the patch suggested in PR
40462, still seeing a bootstrap failure on sparc-linux-gnu, as in PR40352. No
preprocessed source yet.

On sparc64-linux bootstrap worked at rev 147974 but failed at rev 148004 (far
mmachine gcc62). I get the same failure on sparc-linux (farm machine gcc54).

I'll try to get a preprocessed file, another option is to get an account on the
compile farm, procedure here:
