Checking status for configuration 'smoke58x_config.local' (5.8.x)
  Change number 23430 started on Sat Oct 30 17:56:58 2004.
    2 out of 20 configurations finished in 4 hours 17 minutes.
    2 configurations showed failures (F).
    0 failures in the running configuration.
    18 configurations to finish, estimated completion in 1 day 14 hours 32 minutes
    Average smoke duration: 2 hours 8 minutes.

Conclusion (confirmed via Abe's irix -32 machine): -Dusemallocwrap does not
cause errors in -32 mode, just as with -64 mode. (No data as to whether it
does any good, however.) The failures for 'cc -32' (old 32-bit aka -o32, not
-n32) were in Math::Trig at test 24 (ditto Abe's); great_circle_direction's
division (line 141) had a 0 in the denominator (I'm guessing roundoff
errors; note that the -o32 math library is known to be less accurate than
the -n32 and -64 ones; it _may_ be possible to cure this via not optimizing
at -O2 (using -O1 instead or not optimizing at all), but I suspect not from
reading over various manpages; it is possible that usage of -lm43 - only if
using -32! - instead of -lm might help).

Conclusion: 5.9.x in -n32 mode also needs -Uusemallocwrap.

results:

Checking status for configuration 'smoke58x_config.local' (5.8.x)
  Change number 23430 started on Sat Oct 30 17:49:03 2004.

From smoke58x.log, the tests have gotten beyond the miniperl stage without
panics.

Conclusion: -DDEBUGGING does not make a difference.

Given the above results, I will write a patch for hints/irix_6.sh (as in for
all versions of IRIX 6.2+) that will turn off usemallocwrap for -n32 but not
-32 or -64 more, nor for gcc (no idea whether it is needed for gcc or not,
however! Which malloc does Perl complied with gcc on IRIX (which has
usemymalloc='false') use?).
