Jay B: you should check out the code from the trunk and try that, it’s pretty robust — it can handle a non-debugging build of Firefox, which is a pretty big program. And there’s already one bug filed against the port in the Valgrind bug database

Yep – finally! Valgrind coming to OS X!
Awesome!!

Can’t wait for the first alpha version to try it out.
Used valgrind in my day job on Linux and I’m really missing something equally powerful on my Mac OS X tool suite for years now..

My apologies for the incorrect indenting. I had emacs on one machine configured for valgrind-style once upon a time, but lost that configuration later.

No apologies for the rest of the patch. Big ports are always ugly…

BlueMM: I used to work at Melbourne Uni, so I did/do the Brunswick-to-Parkville route along the Upfield bike path and Royal Parade a lot.

For longer rides I usually do the Yarra trail from the CBD round to the Merri Ck at Rushall station, and along Park St in Fitzroy/Carlton.

Hi,
I’m trying valgrind with a tool that reads in text from a filehandle and then pushes it out over the network via a socket connection. Valgrind seems to bail out when the socket is being created. Here’s the output:

valgrind ./bropipe -df /tmp/url-alerts.txt

Note: see also the FAQ.txt in the source distribution.
It contains workarounds to several common problems.

If that doesn’t help, please report this bug to: http://www.valgrind.org

In the bug report, send all the above text, the valgrind
version, and what OS and OS version you are using. Thanks.

Illegal instruction

Looks like some kind of unimplemented functionality that is causing and exception?

Being a fellow Melbournian & bike rider, what’s your usual/favourite bike ride(s)?

I would highly recommend having a way to run at the very least the test suite on a 64-bit machine. 64-bit is very very much the future of Mac OS X. A 32-bit only patch won’t be very useful for very long.

It’s possible someone like vlad, alice or jesse would be able to hook you up with a 64-bit OS X machine to ssh into and at least run tests.

It’s not working nearly well enough to include in Snow Leopard. Also, since Valgrind is GPL, I imagine Apple doesn’t want it included in Snow Leopard.

Great news!

Have you checked with Apple that they are not working on this? Sounds strange to me that Greg puts all that work in and then Apple doesn’t include it in Snow Leopard…but then again, in that case, he probably wouldn’t have released his version just yet.
