bug#61504: 29.0.60; executing byte-code from previous build causes SIGSE

By the way, doesn't the patch switch the restoration order of narrowing and restriction, respectively? Maybe it doesn't matter?

Hmmm, that's a good question! The evaluation order of parameters is unspecified in C,

The problem is not in the evaluation order of params in `save_restriction_save` (this order doesn't matter because the code is pure), it's in `save_restriction_restore`.


Indeed, I initially misunderstood what Mattias said, but after reading it again I got it. This is now fixed.

Thanks!
