Subject: mips: null pointer deref should segfault
X-Git-Tag: TizenStudio_2.0_p2.3.2~208^2~5636^2~30^2~5
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e6e5bd2dd1868b5a244bc572422f585cef579ffb;p=sdk%2Femulator%2Fqemu.git

mips: null pointer deref should segfault

Dereferencing a null pointer causes an exception 0xC (EXCP_AdEL)
instead of EXCP_TLBL. This should also trigger a segfault.
