AddressSanitizer: SEGV on unknown address

[elManto]

Getting an ASAN SEGV report. To reproduce, I just compiled with asan enabled on x86 machine Linux. To reproduce:

./rcc -target=x86/linux file.c , where file.c the following piece of C code:

int main() { printf("Hello World\n"); return 0; }

Here I attach the full ASAN report
