debug_demangle_backtrace

Demangles bt, possibly got from debug_get_raw_backtrace , by replacing addresses with actual function calls and eventually line numbers, if available.

It modifies lines of bt, but skips those it cannot parse.

Note: Getting backtraces only works if the library was configured with --enable-backtraces.

See also debug_get_raw_backtrace

Parameters:

bt	a StringBuilder with a raw backtrace, or null
