[Valgrind-users] "noted but unhandled ioctl 0x2000747b with no size/direction hints" on Mac OS X

[Sean M. <se...@ro...>]

Hi all,

Now that I've purged spaces from my paths :), valgrind has found several
bugs for me. yay!

However, I'm now getting a new error/warning/thingie:

==9399== Warning: noted but unhandled ioctl 0x2000747b with no size/
direction hints
==9399==    This could cause spurious value errors to appear.
==9399==    See README_MISSING_SYSCALL_OR_IOCTL for guidance on writing
a proper wrapper.
==9399== Warning: noted but unhandled ioctl 0x2000747a with no size/
direction hints
==9399==    This could cause spurious value errors to appear.

I've read the README_MISSING_SYSCALL_OR_IOCTL doc, but it gives the
impression that I should be seeing a name instead of a hex number.

I searched bugzilla for these magic numbers, but found nothing.

How to proceed?  Is this a valgrind bug?

Cheers,

PS: I'm a newbie, be gentle! :)
