Reduced test case is:
% cat exclude.c
int version;
int zz1(char *);
static void zz2(int flags)
{
static int initialized = 0;
char xx[4096];
if (initialized)
return;
initialized = 1;
zz2(flags | (version ? 2 : 0));
zz2(flags);
zz1(xx);
}
void zz3()
{
zz2(0);
}
% gcc -v -O -c exclude.c
Using built-in specs.
