Hello, The upstream for quickfix contains a very old embedded library copy [1]. This originally came up in the context of a FTBFS on riscv64. It doesn't seem to be tracked here yet [2].
Debian already has a package for the library in question, called libdouble-conversion-dev. Quickfix upstream recently closed their bug [3] for the FTBFS on which I had mentioned the embedded copy, but the embedded copy is still present. -Alan Beadle [1] https://github.com/quickfix/quickfix/tree/master/src/C%2B%2B/double-conversion [2] https://salsa.debian.org/security-tracker-team/security-tracker/raw/master/data/embedded-code-copies [3] https://github.com/quickfix/quickfix/issues/393
