Hi Pavel, > It doesn't matter, why i do it on such way. *shrug* Okay. I thought you were solving a real world problem, rather than just being an academic exercise in the limits of the GCC compiler. > The quastion is, why g++ cannot compile (without optimisaion, -O0, > -Q) function (even rathner large one), where is only assignation > code? what can be simpler than that? Because GCC is running out of memory. Is your GCC compiled as a 64-bit application? Are you running on a 64-bit OS that supports applications running as 64-bit applications? (Some 64-bit OS's only support 32-bit client applications.) (I'm not even sure if GCC can be compiled as a 64-bit application. I know it can be built to produce 64-bit applications... but that's not relevant.) HTH, --Eljay
