:content
Captures and formats a native backtrace for the current call stack.

This helper is for diagnostics. It is used by runtime error reporting paths and can also be useful in local debugging pages.

Example:


:example
String trace = backtrace_capture();
print(trace == "" ? "(empty in the wasm sandbox; populated by the native crash handler)" : trace, "\n");
