If gcc developers would try to completely clean up all known bugs they would never release a single version. I do not think that instability of GCC preprocessor under WIndows 10 should delay release unless there are other significant problems. It should however be OK to discuss DJGPP problems when used under WIndows 10. We could release DJGPP v2.06 soon enough if really critical problems wuold be found and fixed soon. That would not require so much efforts as current release due to smaller amount of changes About current instability: - nmalloc problems mentioned earlier are not source. They were present also for Windows Vista which I used to build GCC packages available on ftp.delorie.com and they did not prevent me from building GCC. These problems do not appear to be source of difficulties also under Windows 10 - there seems to be no instability in running some other DJGPP programs. I tried program for calculating arbitrary number of decimal signs of number pi I mentioned in earlier message. No problems detected trying to calculate 100000000 decimal signs of pi under Windows 10. That required near 1GB of DPMI memory and took more than 5 minutes per run. - random DPMI corruption would much more likely bite actual compiler not preprocessor due to larger amount of required resources After all that I'm more inclined to think that the problem lies on our side. There could be slight differences between different DPMI providers that could trigger problems. I have some more ideas to try but I would not like to discuss them before trying. It may also take time to fix the problem if really found. So guess we should actually release 2.05 now. Andris
