llvm dev - Jun 2004 - [LLVMdev] getelementptr results in seg-fault.

Hi,

I'm trying to compile and run the following code-snippet:

implementation

uint %fie(uint* %x) {
    %e = getelementptr uint* %x, int 1
    ; %f = load uint* %e
    ret uint 3
}

int %main(int %argc, sbyte** %argv) {
    %z = malloc uint, uint 10
    %g = call uint %fie(uint* %z)
    ret int 0
}

But the getelementptr instruction gives a segmentation fault. Have I
misunderstood its use? I get segmentation faults when I try to compile it
as well.

bash-2.05b$ llvm-as -f test.ll
bash-2.05b$ lli test.bc
Segmentation fault
bash-2.05b$ llc -f test.bc
Segmentation fault

Any ideas of what's wrong?

Hi Tobias,

I tried your test program on the latest CVS code. Everything worked
fine.

Can you tell me which version of LLVM you're using?

Reid.

Hi!

Hmm, ok. I'm using the 1.2 release. Found out that it worked when using
long to index getelementptr, but not when using uint, int or ulong. But
then I'll try with the CVS code instead. Thank you.
