trunk is a little more informative:

In file included from /usr/include/string.h:635:0,
from test3.c:2:
test3.c: In function 'sum':
/usr/include/x86_64-linux-gnu/bits/string3.h:78:42: error: inlining failed in
call to always_inline 'memset': caller function contains cilk spawn
test3.c:16:3: note: called from here
static bool
can_inline_edge_p (struct cgraph_edge *e, bool report,
bool disregard_limits = false, bool early = false)
{
...
else if (inline_summaries->get (caller)->contains_cilk_spawn)
{
e->inline_failed = CIF_CILK_SPAWN;
inlinable = false;
}
for whatever (stupid) reason. Honza added this code with r221706 (without
a testcase). Disabling it works fine (for this testcase).
A workaround is to separate the memset part of the function to a separate
function...
