Subject: This won't work on ppc32 unless you ask for an alt stack with x permissions,
X-Git-Tag: svn/VALGRIND_3_1_0~65
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=4114af13403f36995c4bf565f12260577e7bd0f8;p=thirdparty%2Fvalgrind.git

This won't work on ppc32 unless you ask for an alt stack with x permissions,
since signal returning requires execution of code on the stack.
