From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/gcc.dg/free-1.c | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/free-1.c (limited to 'gcc/testsuite/gcc.dg/free-1.c') diff --git a/gcc/testsuite/gcc.dg/free-1.c b/gcc/testsuite/gcc.dg/free-1.c new file mode 100644 index 000000000..5496c84fd --- /dev/null +++ b/gcc/testsuite/gcc.dg/free-1.c @@ -0,0 +1,26 @@ +/* PR c/36970 */ +/* { dg-do compile } */ +/* { dg-options "-O2" } */ + +extern void free (void *); + +char *p, buf3[10], d; +struct S { char a; int b; } *r; + +void foo (void) +{ + char buf[10], buf2[10], c; + static char buf4[10], e; + char *q = buf; + free (p); + free (q); /* { dg-warning "attempt to free a non-heap object" } */ + free (buf2); /* { dg-warning "attempt to free a non-heap object" } */ + free (&c); /* { dg-warning "attempt to free a non-heap object" } */ + free (buf3); /* { dg-warning "attempt to free a non-heap object" } */ + free (&d); /* { dg-warning "attempt to free a non-heap object" } */ + free (buf4); /* { dg-warning "attempt to free a non-heap object" } */ + free (&e); /* { dg-warning "attempt to free a non-heap object" } */ + free (&r->a); + free ("abcd"); /* { dg-warning "attempt to free a non-heap object" } */ + free (L"abcd"); /* { dg-warning "attempt to free a non-heap object" } */ +} -- cgit v1.2.3
