Could this change have broken gdb? Created hello.c:
#include <stdio.h>
#include <stdlib.h>
int main( int argc, char *argv[] )
{
printf( "%s", "hello world\n" );
exit( 0 );
}
cc --version
FreeBSD clang version 3.4 (tags/RELEASE_34/final 197956) 20140216
Target: i386-unknown-freebsd10.0
Thread model: posix
cc -g hello.c -o hello
gdb ./hello
