The source code of time.c shows that backtrace_symbols() is a c function with headers from /usr/include/execinfo.h. According to its man-page, backtrace_symbols() is implemented in libexecinfo.so

I don't run NetBSD-current. Could it be that its implementation is missing in NetBSD-current?

Here from NetBSD 10:

# nm /usr/lib/libexecinfo.so | grep backtrace_symbols
00000000000016bc T backtrace_symbols

Otherwise, it's more complicated :)
