Other ways to ICE gcc:
///////////////////////
typedef struct S {
unsigned long flags;
}S_t;
typedef S_t __attribute__((__may_alias__)) cmonkey;
S_t *handler(void *vp)
{
cmonkey *cm = vp;
return cm;
}
////////////////////////
typedef struct S {
unsigned long flags;
}S_t;
typedef S_t __attribute__((__may_alias__)) cmonkey;
S_t handler(void *vp)
{
cmonkey *cm = vp;
return *cm;
}
//////////////////////
typedef struct S {
unsigned long flags;
}S_t;
typedef S_t __attribute__((__may_alias__)) cmonkey;
int handler(void *vp)
{
S_t dp;
cmonkey *cm = vp;
dp = *cm;
}
///////////////////
typedef struct S {
unsigned long flags;
}S_t;
typedef S_t __attribute__((__may_alias__)) cmonkey;
int handler(void *vp)
{
S_t * dp;
cmonkey *cm = vp;
*dp = *cm;
}
////////////////////////
Besides a fix, I could use some workaround suggestions.
This itself is an attempted workaround for a suspected
bug involving memcpy, so that won't do.
