Assertion when loading bitcode

I am using GCC 4.3.2 ( Debian 4.3.2-1.1) on x86. I will try out a different compiler.

I tried out Sourcery G++ Lite 2009q1-203 (GCC 4.3.3). I still can’t get lli to run. This time the error is like this:

How do I make this go away? Please could someone point in the right direction.

Thanks

Hi,

>>>>> I am using GCC 4.3.2 ( Debian 4.3.2-1.1) on x86. I will try out a

I tried out Sourcery G++ Lite 2009q1-203 (GCC 4.3.3). I still can't get
lli to run. This time the error is like this:

if the problem is due to a compiler bug, then you should try a very
different compiler version, for example gcc 4.2 or 4.4.

Ciao,

Duncan.

If it's _not_ a gcc miscompilation, you'll need to attach the .bc file
that's crashing lli so someone with an ARM llvm build can try to
reproduce your problem. You'd also need the exact lli command line
you're using, but I see that at the bottom of your crash dump.
