They mostly was caused by inprecision of double arithmetic.
Fixed by changes in how to handle multiple intersections to keep their order right.
Also ST_DISTANCE(GEOM, EMPTY_GEOM) was defined as NULL.

When edges of a polygon coicide, it can form an pike, that is turned into a line after an operation.
In this case a former polygon point can be an end of a single line, and that case wasn't properly handled.

We cannot cut a line from a polygon. So if the polygon fits the condition, and
the intersection of a line and the polygon doesn't, we just skip the line.
That rule wasn't applied if the line start was inside the polygon, which leaded
to the assertion.

the intersection point treated as it doesn't belong to the line.

That crash happened with the complicated topology of the result.
If we found a hole in a polygon whose outside border was already
found, we need to paste the hole right after it and respectively
shift polygons after it. Also we need to update poly_position fields
in these polygons. That last thing wasn't properly done that led to the
crash.
To fix that we keep the list of the found polygons and update the
poly_positions that are bigger or equal to where we placed the next hole.

Collections were treated mistakenly, so the counter for the final UNION operation
received the wrong value.
As a fix we implement Item_func_buffer::Transporter::start_collection() method,
where we set the proper operation and the operand counter.
start_poly() and start_line() were also modified to function correctly for the
polygon as a part of a collection.

If the result contains a polygon with a hole, consequitive shapes weren't calculated
properly, as the hole appeared as shape in the result, but actually it's a single shape
with the surrounding polygon. It's more natural to use the size of the result as
a border instead of the number of resulting shapes.

The previous patch partially fixed things by waiting for the old dump thread
on the master to exit before injecting the DBUG error. This prevents the error
injection going to the wrong thread.
However, there is still the problem that the old dump thread may never exit,
causing the wait to time out. This happens if the dump thread manages to write
all events down the socket before the socket is closed by the slave. The
master dump thread only checks for slave gone when writing a new event, so if
no new events are generated, old dump threads can hang around forever on the
master after the slave disconnects.
Fix by explicitly killing the old dump thread if it is still around.

This change fixes a non-fatal uninitialized memory copy.
The function generate_derived_keys did not take into account the fact
that the last element in the array of keyuses could be just a barrier
element. In some cases it could lead to a crash of the server.
Also fixed a couple of other bugs in generate_derived_keys: the inner
loop in the body of if this function did not change the cycle variables
properly.
The reason for this is that BLOCK_RECORD format is not good when there is a lot of duplicated keys as it first writes the data (to get the row position) and
then writes the key (and thus checks for duplicates).
