"The build timeout" build failure(s)
clang 3.2
The binary produced by clang is wrong when built with -D_FORTIFY_SOURCE=2.
For example, the code:
#include <stdlib.h>
#include <unistd.h>
#include <fcntl.h>
int main ()
{
char *data;
int pagesize;
int fd, foo;
pagesize = getpagesize ();
fd = open ("conftest.mmap", O_RDWR);
data = (char *) malloc (pagesize);
foo = read (fd, data, pagesize);
}
compiled with:
clang++ -o conftest -g -O2 -D_FORTIFY_SOURCE=2 conftest.cpp
will be stucked in an infinity loop.
