Most likely the thing that's happening is that check_sblock takes a "long"
time during which there's a higher probability for a signal to arrive and
the bug itself is that one of the signal handlers does some string
allocation (or some other manipulation of those data structures).
I'd try something like
eassert (!in_allocate_string_data);
in_allocate_string_data = 1;
...
check_sblock();
...
in_allocate_string_data = 0;
BTW, it's possible that -DSYNC_INPUT fixes the bug.
