Comment 6 for bug 1841987

Based on etc/build.info, it is not from cengn.

I tried to get a similar libvirt debuginfo from http://mirror.starlingx.cengn.ca/mirror/starlingx/release/2.0.0/centos/outputs/RPMS/std/libvirt-debuginfo-4.7.0-1.tis.101.x86_64.rpm

Based on kernel log:
./var/log/kern.log:2019-08-29T07:58:32.687 controller-0 kernel: info [ 4068.847731] libvirtd[713586]: segfault at 8 ip 00007f050e93c73c sp 00007ffea29a2130 error 4 in libvirt.so.0.4007.0[7f050e8b7000+334000]

All of them were crashed at same position: 8573c @ libvirt.so.0.4007.0

Based on the disassembly of libvirt.so.0.4007.0 (it might not exactly same as your private build):

util/virauth.c:64
int
virAuthGetConfigFilePathURI(virURIPtr uri,
                            char **path)
{
    size_t i;
    const char *authenv = getenv("LIBVIRT_AUTH_FILE");
    VIR_AUTOFREE(char *) userdir = NULL;
... ...
    if (uri) {
        for (i = 0; i < uri->paramsCount; i++) {
            if (STREQ_NULLABLE(uri->params[i].name, "authfile") &&
                uri->params[i].value) {
                VIR_DEBUG("Using path from URI '%s'", uri->params[i].value);
line64 ==> if (VIR_STRDUP(*path, uri->params[i].value) < 0)
                    return -1;
                return 0;
            }
        }

Could you please provide the debuginfo rpm? It needs to double check whether above disassembly is match?
