fixes #25306
```nim
type
StackTraceEntry* = object ## In debug mode exceptions store the stack trace that led
## to them. A `StackTraceEntry` is a single entry of the
## stack trace.
procname*: cstring ## Name of the proc that is currently executing.
line*: int ## Line number of the proc that is currently executing.
filename*: cstring ## Filename of the proc that is currently executing.
when NimStackTraceMsgs:
frameMsg*: string ## When a stacktrace is generated in a given frame and
## rendered at a later time, we should ensure the stacktrace
## data isn't invalidated; any pointer into PFrame is
## subject to being invalidated so shouldn't be stored.
when defined(nimStackTraceOverride):
programCounter*: uint ## Program counter - will be used to get the rest of the info,
## when `$` is called on this type. We can't use
## "cuintptr_t" in here.
procnameStr*, filenameStr*: string ## GC-ed alternatives to "procname" and "filename"
```
