Backported the fix from 10.0, pushed into 10.0-base
The problem appeared with the following revision:
revno: 3486
revision-id: sergii@pisem.net-20130128140636-y4getr57mbf0xq9y
parent: sergii@pisem.net-20130124165225-gczln6zrzi4lz4bx
committer: Sergei Golubchik <sergii@pisem.net>
branch nick: 10.0-base
timestamp: Mon 2013-01-28 15:06:36 +0100
message:
my_alloca() when it's mapped to malloc() works most certainly MY_THREAD_SPECIFIC
and I presume it was fixed by the following revision, but in 10.0 only:
revno: 3496
revision-id: sergii@pisem.net-20130131203221-2xsc0dp0r916bnu1
parent: sergii@pisem.net-20130131145126-4xnbqhr4hmuij61v
committer: Sergei Golubchik <sergii@pisem.net>
branch nick: 10.0
timestamp: Thu 2013-01-31 21:32:21 +0100
message:
fix for a valgrind builds.
my_alloca() cannot have MY_THREAD_SPECIFIC, because can be used
outside of the THD context.
