Seems to be var-tracking, -fno-var-tracking is fast here.

Reduced test-case where adding -g takes 20x longer to compile:

struct S0 {
signed f0 : 5
};
union U1 {

};
static int g_2 = 0xE60F951FL;

static signed char g_61 = 0x39L;
static unsigned char g_69 = 0xA9L;
static signed char g_113 = 7L;
static short g_136 = 0;
static uint64_t g_138 = 0x3DAD6103D800CEE5LL;
static int g_257 = 1L;
static struct S0 g_513;
static int g_1457 = 0xA3396F68L;

int *l_1463 = &g_1457;
(*l_1463) ^= func_5(0, (+func_14(func_17(l_332, g_113), g_513)), l_1264[3],
l_333.f0);
}
}
static union U1 func_17(int p_19, uint16_t p_20) {
p_20 = 1;
for (p_20; (p_20 <= 8); p_20 += 1) {
