Subject: Call VG_(unknown_SP_update) each time we switch to a new thread. This
X-Git-Tag: svn/VALGRIND_3_1_0~162
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=dd590a7f95a1ad718712faceed7614c7b7cb66e8;p=thirdparty%2Fvalgrind.git

Call VG_(unknown_SP_update) each time we switch to a new thread. This
ensures that current_stack is switched to the new thread's stack so
that we don't ignore the next stack update and hence fail to mark
memory that should be valid as valid.
