Hi,
I've tinkered around with this problem. Commenting out the 'verify( l
bigl );' line in src/mongo/db/btree.h solves the assertion failure
problem, and mongodb starts and runs. However, after reviewing the
code it seems this 'start' unit test is only actually testing if the
thing can 'subtract integers.' I'm very puzzled as to why it is
failing, it's bombing out when it does 'verify ((-1 - 0xf12312)0)'.
which seems trivial.
The code that runs the unit test/StartupTest is simple, but i haven't
yet found the 'verify' macro, at least i believe it's a macro.
Anyhow, commenting out the test line gets mongodb running, but I'm
wondering what other problems there could be. (?)
I found that compiling with base gcc avoids the startup problem, so
this indeed seems to be an issue related to building with clang. clang
builds mongodb without error, however running the mongodb compiled
with clang fails during 'startuptest'.
IMHO It would be good to track down the problem, at least understand
the cause, but at this moment it seems like compiling mongodb with gcc
is the way to go.
I've updated the port to use the latest release/ 2.2.2 version of
mongodb, I'll submit a PR in a bit, (it does not appear to have
