#4 solaris8 - segfault in displayEnd()

[Anonymous]

Using this silly case:
$ ./bar -if bar -of junk
155.3KB at 0.0B/s eta: 0:00:00 100% [=====================================================================================]
Copied: 683226217705696zsh: segmentation fault (core dumped) ./bar -if bar -of junk
$ file bar
bar: ELF 32-bit MSB executable SPARC Version 1, dynamically linked, not stripped

Work around:
Modify CFLAGS to include '-m64' which creates a 64-bit executable.

A related bug, also fixed by the -m64, is that if you specify -s
<size> it never does anything.

This is because this code in safe_mul():

    multiplier = 1;
    multiplier *= 1000;
    multiplier *= 1000;
    multiplier *= 1000;
    multiplier *= 1000;
    multiplier *= 1000;
    multiplier *= 1000;

ends up setting multiplier to 2808348672

multiplier:1
multiplier:1000
multiplier:1000000
multiplier:1000000000
multiplier:3567587328
multiplier:2764472320
multiplier:2808348672

Then when it divides by 10 a few lines later...

multiplier:280834867
multiplier:28083486
multiplier:2808348
multiplier:280834
multiplier:28083
multiplier:2808
multiplier:280
multiplier:28
multiplier:2
multiplier:0

Whups! If multiplier is 0, then the loop goes no place.

Hmmm.... 1000000000 * 1000 = 3567587328 ?
Can you send me your config.log file?

[Christian Höltje]

I'm not a big user of Source Forge....how do I attach a file?

[Christian Höltje]

I put it here: http://docwhat.org/files/tmp/bar-solaris-config.log

Feel free to attach it to this bug, if you have that ability. :-/

[Michael Peek]

Something must be wonky somewhere. I can't resolve the hostname docwhat.org. Can you email it to me at michaelpeek@sourceforge.net?

Also, I'm working on 1.11.0, and I'm adding code that will hopefully correctly detect the ability to use the -m64 flag. Would you be up for trying it out when it's ready?

[Michael Peek]

Whoops... michaelpeek@sourceforge.net doesn't seem to work anymore. Try peek@tiem.utk.edu instead.

[Michael Peek]

Nevermind, I got it. For some reason I couldn't resolve docwhat.org from work, but I could got it once I got home. Thanks!
