command line: gcc -ftest-coverage -c a.c

compiler output:
a.c: In function ‘f’:
a.c:2:1: error: expected declaration or statement at end of input

preprocessed file:
# 1 "a.c"
# 1 "<command-line>"
# 1 "a.c"
int f()

bug description:
Since the compiler exited with error, it is expected that the files it was
generating be cleaned up. However, a.gcno file which is one of them is left not
deleted.
