Re: bzr commit into mysql-5.1-innodb branch (marko.makela:3464) Bug#53593

[Marko Mäkelä]

Hi Davi,

I decided to work today, so that I can have June 7 off. I tried more 
liberal use of VALGRIND_MAKE_MEM_NOACCESS, but I would have had to 
"undo" it (declare memory addressable) in certain places, which would 
have defeated the purpose of Valgrind.

I posted a revised version of the patch. On top of that, I got one 
further idea: add MEM_CHECK_ADDRESSABLE to TRASH. Currently, the 
non-SAFEMALLOC version of TRASH "blindly" declares the memory 
addressable by MEM_UNDEFINED.
