IRIX core dump (even with gcc)
larb0b opened this issue · comments
This issue is already mentioned in the README, but I figured it was probably worth mentioning that the same issue occurs even when built with GCC 9.2.0.

Since IRIX is big-endian, all those htons()s and htonl()s that crash like that can be turned into no-ops. I just haven't gotten around to doing it. PRs accepted.
Okay, give it a try. If you get it working with gcc, then adjust the recipe and PR it. I only have MIPSPro on my systems.
Yep, it seems to work fine with GCC 9.2.0 from SGUG-RSE with no adjustments. Let me know if you'd like me to submit a PR removing the warning about it not being tested on GCC, but otherwise it should be fine without any changes.
What I think I'll do is just mark it as a "contributed" configuration. gcc 9 is kinda new, so it might be good to see how well it works with older ones (it should work fine, but who knows). I'll close this out; advise if you do find a bug somewhere since I might not have gotten all the weirdo pointers. SPARC is next.
