Is this related to PR35493?
A possibly related cygwin failure was also reported here.

When using -fstrict-aliasing the function LC1_f15 below gets miscompiled. More
precisely, the va_list object is only partially assigned. The system fails to
set the frame size or something similar. In the assembler I see
/* local function %F15 */

Can you provide an executable testcase that abort()s if the miscompilation
happens?

However, I had to split the test case into two different files, for otherwise

This one turned up during my testing of SPREAD on wide character strings, but
it turns out that it already happens on default character variables. It looks
like the front-end doesn't fill the return array descriptor well.
