Wrong stack trace attached, correct is:

The key is:
```
#7  0x000055555559d3db in gc_malloc ()
#8  0x0000555555599875 in _d_newclass ()
#9  0x00005555555a3029 in core.runtime.defaultTraceHandler(void*) ()

#11 0x000055555559d942 in _d_createTrace ()
#12 0x0000555555598cbe in _d_throwdwarf ()
```

So it means we hit
https://github.com/dlang/druntime/blob/fd9a45448244fb9dd4326520ad8526c540895eb0/src/core/runtime.d#L695
But that shouldn't be possible, since this function is guarded by a
`GC.inFinalizer` check that would lead to it returning...

--- Comment #4 from moonlightsentinel@disroot.org ---
The problem here is that this line [1] is executed before the exception is rethrown - which calls `_d_throwdwarf` and ends up trying to allocate the DefaultTraceHandler.
