Subject: c++: ICE with [[trivial_abi]] [PR125022]
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=fb7d898dbc4d0b1bf099cae8635e205fa8981dc2;p=thirdparty%2Fgcc.git

c++: ICE with [[trivial_abi]] [PR125022]

We don't mess with cleanups at template parsing time.

	PR c++/125022

gcc/cp/ChangeLog:

	* decl.cc (store_parm_decls): Only do trivial_abi stuff when
	!processing_template_decl.

gcc/testsuite/ChangeLog:

	* g++.dg/cpp0x/attr-trivial_abi7.C: New test.
