Hi,
My issue might be related to previous posts about "signal_impl::clear()"
and maybe even "sigc::internal::signal_emit1 SIGSEGV".
Namely, the following code fails with segmentation fault:
sigc::signal<void> sig;
sig.connect([&sig]() { sig.clear(); } );
sig();
However it does not fail if handler is disconnected using:
sig = sigc::signal<void>();
or when sigc::connection is used to disconnect the signal/handler linkage.
Worth to note that sigc::slot doesn't have the same problem, it can be
safely disconnected from inside the handler using slot.disconnect().
Is it a bug or some undocumented limitation? It might not be very logical
thing to clear all slots connected to the signal from one of its handlers
though. If that is the case, I think at least docs should tell that.
I reproduced the issue on 2.8.0 and 2.9.3. Didn't try 2.99 yet.
BR, Andrey
