[Valgrind-users] Valgrind trunk on Mac

[Nikolas Z. <zim...@kd...>]

Good evening valgrind crowd,

I'm a happy valgrind user for years, and even on Mac since a while. I've used it to debug WebKit with a build from around mid-March 2012 (valgrind-3.8 trunk) w/o problems.
I've updated to latest ToT and it no longer works.

Basically I'm facing the same issues as described in http://www.mail-archive.com/val...@li.../msg03549.html, except that I can't get the "sudo" trick working for anything but TextEdit.

As I knew it worked some months ago I did some bi-sect builds:
r12734 - FAILS (vex trunk): ToT
r12653 - FAILS (vex trunk)
r12630 - FAILS (vex trunk)
r12620 - FAILS (vex trunk)
...
r12458 - WORKS (vex 2267)


Narrowing this even more:
r12500 - FAILS (vex 2277)
r12487 - FAILS (vex 2274)
r12483 - FAILS (vex 2272)
r12476 - FAILS (vex 2270)
r12466 - FAILS (vex 2269)
~~~~~~~~~~~~~~~~~~~~~
r12465 - WORKS (vex 2269)
r12464 - WORKS (vex 2269)
r12460 - WORKS (vex 2269)
r12459 - WORKS (vex 2268)
r12458 - WORKS (vex 2267)

So it's precisely commit r12466 which makes valgrind fail on at least Lion.

I hope this helps to fix the regression so that valgrind is usable again for us Mac ppl :-)

Thanks in advance for your help,
Niko
