./configure --prefix=/usr --build=x86_64-pc-linux-gnu
- --host=x86_64-pc-linux-gnu --mandir=/usr/share/man
- --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc
- --localstatedir=/var/lib --libdir=/usr/lib64 --with-libatomic-ops=yes
- --enable-cplusplus --disable-threads
no make flags AFAICS, just ordinary make/make install, no patches.

I can try other versions, but perhaps someone on your side should
attempt to reproduce by recompiling their boehm-gc with
- --disable-threads. This bug has existed for quite some time and for
multiple guile and I assume boehm-gc versions.

Please try to reproduce and then maybe we can do that.
