nm output looks different for mpd:

# nm /usr/pkg/bin/mpd | grep 
_ZSt17rethrow_exceptionNSt15__exception_ptr13exception_ptrE
 U 
_ZSt17rethrow_exceptionNSt15__exception_ptr13exception_ptrE@@CXXABI_1.3.3

perhaps the CXXABI suffix is the issue?

I see this as well:

# nm /usr/lib/libstdc++.so |grep -i 
_ZSt17rethrow_exceptionNSt15__exception_ptr13exception_ptrE
00076ca1 T _ZSt17rethrow_exceptionNSt15__exception_ptr13exception_ptrE

Not sure why mpd is unhappy.

I have this symbol, though:
> nm /usr/lib/libstdc++.so |grep -i rethrow
00076ca1 T _ZSt17rethrow_exceptionNSt15__exception_ptr13exception_ptrE

Probably related:

dnl Determine whether std::exception_ptr symbols should be exported with
dnl the symbol versions from GCC 4.6.0 or GCC 7.1.0, depending on which
dnl release first added support for std::exception_ptr. Originally it
was
dnl only supported for targets with always-lock-free atomics for int,
but
dnl since GCC 7.1 it is supported for all targets.

gcc7 problem: mpd doesn't start

2019-02-11 Thread Thomas Klausner 
Hi!

Since upgrading to a snapshot (8.99.34/amd64) with gcc7,
audio/musicpd's mpd binary (built on 8.99.30 with gcc6) does not start
any longer. It fails with:

mpd: Undefined PLT symbol 
"_ZSt17rethrow_exceptionNSt15__exception_ptr13exception_ptrE" (symnum = 107)
