Hi Maxim,

vect.exp=vect-simd-clone-10.c should trigger this.

Running vect-simd-clone-10.c produces the leftover
vect-simd-clone-10a.c.126t.vect.

But if vect-simd-clone-10a.c is run afterwards, then
vect-simd-clone-10a.c.126t.vect is first overwritten, and then cleaned up.

So whether the file is still there after the test run depends on whether 10a is
run after 10 in the same testdirectory.


Reproduced it with a fresh build from r220825:
...
$ make -k -j5 check RUNTESTFLAGS=vect.exp=vect-simd-clone-10.c
--target_board=unix

  ...

$ ls lean/build/gcc/testsuite/gcc*
