Starting over with a breakpoint on pkgconf_cache_add shows that this is happening on the very first call to that function. It happens when client->cache_count is incremented on line 135, just before the realloc: ++client->cache_count; client->cache_table = pkgconf_reallocarray(client->cache_table, client->cache_count, sizeof (void *)); which can only mean that different compilation units have seen different definitions of the pkgconf_client_t type. And here we notice that the latest build of pkgconf is version 2.1.0 from 12 February 2024, and the latest build of perl-PkgConfig-LibPkgConf is perl-PkgConfig-LibPkgConf-0.11-18.fc40 from 29 February 2024 ... but it hasn't gone stable yet. The version you are getting in F40 mock is perl-PkgConfig-LibPkgConf-0.11-17.fc40 from 25 January 2024, built against pkgconf 1.9.5, which had a different definition of pkgconf_client_t. Your choices are to wait for the F40 beta freeze to end, or lobby for a freeze exception for the perl-PkgConfig-LibPkgConf update.
