recursionlimit mystery!

[Sebastien Nouat]

Hi Bruce,

Good news: if you have a look at the bug report, the last comment is a 
link to the GitHub pull request in which the bug is addressed.

The milestone of the pull request is 7.1.0 RC 1, so in the next version 
of LiveCode 7.1 that will be released, the bug will be fixed :)

Regards,

Sébastien

However, in 6.x.x they were using 32-bit numbers, so my setting a very high recursion limit actually did have an effect. They confirm that this is a bug. No promise on the timing of a fix, though.
