Thanks for the report.

However, this patch is a security fix, so reverting it is not so nice
either.

Since it seems that using another optimisation level works arorund the
issue, I would be more inclined to change that, e.g. to -Os, as the
reporter seems to imply it works for them.

Would you please send a patch with such a workaround, please?

Regards,
Yann E. MORIN.
