For this C code:
int globus_i_GLOBUS_GRIDFTP_SERVER_debug_handle_1;
int globus_l_gfs_ipc_unpack_data__sz;
static void globus_l_gfs_ipc_unpack_cred(len) {
if (globus_i_GLOBUS_GRIDFTP_SERVER_debug_handle_1)
globus_i_GLOBUS_GRIDFTP_SERVER_debug_printf("", __func__);
}
static void globus_l_gfs_ipc_unpack_data(len) {
for (; globus_l_gfs_ipc_unpack_data__sz;)
len--;
len -= 4;
len -= 4;
globus_l_gfs_ipc_unpack_cred(len);
}
void globus_l_gfs_ipc_reply_read_body_cb() { globus_l_gfs_ipc_unpack_data(); }
compiled by recent gcc, does this:
$ /home/dcb/gcc/results.20211105/bin/gcc -g -O2 -c bug770.c
In function ‘globus_l_gfs_ipc_unpack_data.isra’:

The fault first seems to occur sometime between git hash d3f7a2fa64f8777c
