[Valgrind-users] valgrind/memcheck and programs using mmap()

[<Dan...@ba...>]

Hi,

The program I am debugging does a large mmap()

Some small mmap() calls seem to work, but the large mmap(), for an 80GB
file, results in EINVAL

I've verified that the offset is 0 and the mapping size is a multiple of
getpagesize().  The mmap() does work when not using valgrind.

Is there some kind of mmap() restriction or size limit with valgrind?  I
searched for mmap in the documentation and didn't find anything.

Is there anything I can do to get valgrind to work with this program, or
an alternative tool I can use?  The reason for using valgrind is to
locate a memory leak.

Regards,

Daniel
