Trying to run the attached osl/oso with testshade crashes in LLVM build:
./oslc test_return_bug.osl
./testshade test_return_bug
It's due to eternal recursion, this is repeated a few thousand times when run
through gdb:
#9 0x0000000100195a66 in OSL::pvt::llvm_gen_loop_op (rop=@0x7fff5fbfe8d0,
opnum=0) at /Users/brecht/dev/osl/src/liboslexec/llvm_instance.cpp:2606
#10 0x000000010018c59b in OSL::pvt::RuntimeOptimizer::build_llvm_code
(this=0x7fff5fbfe8d0, beginop=0, endop=6, bb=0x104018dc0) at
/Users/brecht/dev/osl/src/liboslexec/llvm_instance.cpp:3674
I think the dowhile op to deal with middle of function return is wrong, perhaps
the start label of the body should be 1 instead of 0 in the .oso file?
Tested on with svn revision 864 on Mac.
