Alexey Kopytov 9cb84f8466 Bug #45796: invalid memory reads and writes when altering merge ... and base tables myrg_attach_children() could reuse a buffer that was allocated previously based on a definition of a child table. The problem was that the child's definition might have been changed, so reusing the buffer could lead to crashes or valgrind errors under some circumstances. Fixed by changing myrg_attach_children() so that the rec_per_key_part buffer is reused only when the child table have not changed, and reallocated otherwise (the old buffer is deallocated if necessary).		2009-07-10 17:34:03 +06:00
