@alfkil

1) it doesn't seem to be Amigaos core releated
2) it doesn't seem to be windows related...
3) it might be apple related since they do deal with something called unwinding in the UI, there is a specific library called libunwind (IRC) on savannah.org.

[b]The libunwind project[/b]
[
center]The primary goal of this project is to define a portable and efficient C programming interface (APIto determine the call-chain of a programThe API additionally provides the means to manipulate the preserved (callee-savedstate of each call-frame and to resume execution at any point in the call-chain (non-local goto). The API supports both local (same-process) and remote (across-processoperation. As suchthe API is useful in a number of applicationsSome examples include:[/center]

[
b]exception handling[/b]
The libunwind API makes it trivial to implement the stack-manipulation aspects of exception handling.
debuggers
The libunwind API makes it trivial 
for debuggers to generate the call-chain (backtraceof the threads in a running program.

[
b]introspection[/b]
It is often useful for a running thread to determine its call-chain. For examplethis is useful to display error messages (to show how the error came about) and for performance monitoring/analysis.

[
b]efficient setjmp()[/b]
With libunwindit is possible to implement an extremely efficient version of setjmp(). Effectivelythe only context that needs to be saved consists of the stack-pointer(s).


so my answer is somehow either libunwind has been put as a dependency into Qt 6.1.2
or you have somthing that enables macintosh/iOS/tvOS code.
