Bug #36172 insert into compressed innodb table crashes

Description:
while inserting into a compressed innodb table, we got a crash:

mysqld.exe!mtr_set_log_mode
mysqld.exe!page_zip_reorganize
mysqld.exe!page_cur_insert_rec_zip_reorg
mysqld.exe!page_cur_insert_rec_zip

How to repeat:
uploading testcase later.

after crash recovery, check table crashes on this table.

Assertion failure in thread 2404 in file .\btr\btr0btr.c line 3235
n: page_get_n_recs(page) > 0 || (level == 0 && page_get_page_no(page) == dict_index_get_page(index))

import this. the check table crashes.

I forgot to mention you should first run these to setup the file format:

SET GLOBAL innodb_file_format=“Barracuda”;
SET GLOBAL innodb_file_per_table=ON;

Sunny has a patch for this.

He improves the split algorithm to pick the right split place in btr0btr.c.

Some other place may break because we allow records > page size / 2, but let us see if we get more bug reports.

The patch was committed as r2453.
