Re: [nhc-bugs] nhc98 1.18, gcc 3.4 and FC3

I cannot compile nhc98 1.18 on Fedora Core 3 with gcc 3.4.3. The same was the case with nhc98 1.17 and 1.16. Here is the problem:

OS allocated a heap in high memory (>0x80000000) which breaks this program's run-time system. hpStart=0xb7e5e008, hpEnd=0xb7ed3308

Yes, we know about this bug, hence the error message. Unfortunately, it is tricky to fix, because both the runtime interpreter and the garbage collector use the highest-bit of a heap address for some internal purposes. However, we have a student who has sketched out some potential solutions to the problem, and are hopeful that it can be fixed in the next month or two. Regards, Malcolm
