Description Sergei Trofimovich 2021-12-04 17:26:58 UTC
Noticed as an ICE in tpm2-tss-3.0.3 against weekly gcc-12 snapshot. Here is th extracted example:

$ cat a.c.c
// gcc-12.0.0 -O2  -c a.c.c -o a.o
struct {
  char sm3_256[32];
typedef struct {
  short size;
  char buffer[sizeof(TPMU_HA)];
typedef struct {
  TPM2B_DIGEST auths[3];

void Tss2_Sys_Clear(TSS2L_SYS_AUTH_COMMAND);

void sysContext(void) {
  TPM2B_DIGEST nonce = {};
  TSS2L_SYS_AUTH_COMMAND sessionsDataIn = {{nonce}};

$ gcc-12.0.0 -O2  -c a.c.c -o a.o
during RTL pass: sched2
a.c.c: In function 'sysContext':
a.c.c:19:1: internal compiler error: Segmentation fault
   19 | }
