[Tinycc-devel] [BUG] assertion failure when compiling initialization of array of structs on x86_64

[Eric Biggers]

Hello,

When I tried compiling some of my code with tcc, I encountered an assertion
failure, which I have reduced to the following minimal example:

struct S {
        long a;
};

void f(struct S *x)
{
        struct S y[1] = { *x };
}

$ tcc -c bug.c
tcc: x86_64-gen.c:418: load: Assertion `((ft & VT_BTYPE) == VT_INT) || ((ft & 
VT_BTYPE) == VT_LLONG) || ((ft & VT_BTYPE) == VT_PTR) || ((ft & VT_BTYPE) == 
VT_ENUM) || ((ft & VT_BTYPE) == VT_FUNC)' failed.
Aborted (core dumped)
