Subject: bug/segmentation fault on ia64 (altix)
Hello, First I'd like to thank you for this very nice and useful package. The hardwire function causes a segmentation fault on ia64 architecture (ALTIX itanium with 16 procs running a Suse linux) with perl 5.8.6. I think I fixed the problem, the problem was that a pointer does not fit on an unsigned int on that architecture. Furthermore the address was stored in a rV rather than in a iV. Here's the patch for Mmap.xs --- Mmap.xs 2003-12-15 11:08:21.000000000 +0100 +++ ../Mmap.xs.fixed 2005-11-17 18:28:50.829053839 +0100 @@ -125,7 +125,7 @@ SV * hardwire(var, addr, len) SV * var - unsigned int addr + IV addr size_t len PROTOTYPE: $$$ CODE: @@ -194,7 +194,7 @@ SvCUR_set(var, len); SvLEN_set(var, slop); SvPOK_only(var); - ST(0) = sv_2mortal(newSVnv((int) addr)); + ST(0) = sv_2mortal(newSViv((IV) addr)); SV * munmap(var) I hope that you'll find it useful. Thanks again bye Karl Forner

This also works for me but with all the patches I've sent in, the patch looks like this now.
