Regex is unreliable on K/N #3
Description
Describe the bug
The Kotlin/Native regex engine has known issues with stack overflowing, and as such is extremely unreliable on iOS in my testing. Here are some youtrack issues about it:
https://youtrack.jetbrains.com/issue/KT-35508/EXCBADACCESScode2-address0x16d8dbff0-crashes-on-iOS-when-using-a-sequence-from-map-etc
https://youtrack.jetbrains.com/issue/KT-39789/Segfault-in-KotlinNative-regex-interpreter
https://youtrack.jetbrains.com/issue/KT-46211/KotlinNative-Stack-overflow-crash-in-Regex-classes-with-simple-pattern-and-very-large-input
https://youtrack.jetbrains.com/issue/KT-53352/Native-iOS-Crash-when-using-regex-newSingleThreadContext
I ran into this in my own code, and was only able to workaround the crash by injecting a native regex implementation (i.e. using NSRegularExpression), but then I crashed when calling into this library since it uses Regex behind the scenes 😄

Additional context
The youtrack mentions increasing stack size should help, but I was unable to get that to work in my testing. Maybe I wasn't doing it right though.
Really just opening this ticket for broader awareness. I'm not sure the best approach to fixing it other than possibly rewriting using native regex. The jetbrains team does not seem keen to fixing it on their end.
