Only found one of these in lvm_tab_vg_check_exist.c
But it cores in the lvm_tab_read.c function at the else if
around line 70 (not sure because of my debug code)
The below code is the problem.
else if ( ( buffer = malloc ( stat_b.st_size)) == NULL) {
ret = -LVM_ELVM_TAB_READ_MALLOC;
I placed debug statements in it to see this.
Note that stat_b.st_size = 8
I hope this helps. I do not know enough (yet) about the code to know what buffer is
and why it is setup this way.
