Should core.stdc.signal.signal be nothrow @nogc??

[Bottled Genie via Digitalmars-d]

Can someone help me?

How can I call core.sys.linux.execinfo:backtrace from a 
core.stdc.signal: signal handler? The problem is that signal has 
been declared with @nogc in druntime and backtrace does not have 
that attribute.
