ABI incompatible change on `kotlinx.datetime/LocalDateTime.Companion.parse` function in 0.6.0 release

[StylianosGakis]

This comes from the discussion here https://slack-chats.kotlinlang.org/t/16634293/trying-out-new-kotlinx-datetime-0-6-0-rc-version-and-getting#44912a7d-4923-4870-96b3-872a2a526992
As noted by Benoit, it looks like this change here f18cb89#diff-b1fa2bed442da9d0bb3e4a64b49454763afa5ee6358da76838a8a38654324ca1R174 is what has started producing this crash.
I am not sure if the ABI compatibility is expected to be held with these 0.x versions, but it'd be interesting to hear your thoughts on this.

The answer is, the library is experimental, as you noticed, so we make no binary compatibility guarantees. Even for stable libraries, for Native, ensuring binary compatibility is work-in-progress, and as is, is done on a best effort basis (as opposed to the JVM, where we have strict binary compatibility guarantees for stable API).

Here's some code that could potentially fix this: #357 If someone could build our library with this PR and check if the problem disappears, it would be great. Or someone could give us a reproducing project so we could check this ourselves.

yeah, confirmed here that this fixed the issue https://kotlinlang.slack.com/archives/C01A6KM1SBZ/p1709295909524949?thread_ts=1709291527.353039&cid=C01A6KM1SBZ
