Package: valgrind
Version: 1:3.5.0-3
Hi,
With the default suppressions, even a simple “hello world” program
appears to have errors:
$ cat hello.c
#include <stdio.h>
int main(void)
{
puts("hello");
return 0;
}
$ gcc -Wall -W -o hello hello.c
$ valgrind ./hello

[ and so on ]
Probably ld.so is using some optimization that involves reading
uninitialized data. I work around this by using a suppression file
to ignore everything from ld.so.
Is this a known problem? How can I help to fix it?
