The is an AIX bug, not a GCC bug. I'm not yet convinced that this is the case. It could well be that the assembler (or linker) is being more strict in how it interprets code. Does anyone here have the IBM XL compiler? It would be interesting to compare the assembly that it produces (I presume it can be made to generate assembly even if it normally emits object code directly) for the minimal test case to GCC's.
