MacOS "dyld[58144]: missing symbol called" on import

[jason laughman]

I recently built and installed GnuPG and required libraries from scratch.  What led me down that road was I wanted to update bash on my MacOS 14.7 (Sonoma) machine and needed to verify the download.  All of this was done manually from the CLI using configure & make, not a package manager.  I had to make two changes to get all the reqs to build, one was a three-line patch to fix environ not being created (I forget which package that was, maybe libgpg-error), and another was to add std=gnu98 to CFLAGS for libassuan to fix a duplicate symbol error.  Other than those two changes, everything compiled and installed cleanly and the gpg binary mostly appears to work, but importing keys fails thusly:

$ gpg -v --import ./sign.asc
gpg: enabled compatibility flags:
gpg: pub  rsa3072/BCEF7E294B092E28 2017-03-17  Andre Heinecke (Release Signing Key)
dyld[58268]: missing symbol called
Abort trap: 6

This happens with 2.5.1 and 2.4.5 when using a file as an arg, redirecting stdin, or c&p the contents of sign.asc directly.  sign.asc is the ASCII contents of https://gnupg.org/signature_key.asc.  I also tried with the .asc of the bash maintainer and got the same results.

If I try to verify a .sig, I get this (I understand this is expected behavior, I’m just showing that the binary I built works in other use cases):
$ gpg -dv gnupg-2.5.1.tar.bz2.sig
gpg: enabled compatibility flags:
gpg: assuming signed data in 'gnupg-2.5.1.tar.bz2'
