5.4-RELEASE fails libpthread tests

[Lewis Saunders]

Hi,

Is it normal for most of the tests in /usr/src/lib/libpthread/test/ to fail? 
I've just upgraded from 5.3-RELEASE to 5.4-RELEASE, and running make there 
gives:

I'm afraid I never thought to run the tests on 5.3. The guard tests also 
dump core:

Core was generated by `guard_b'.
Program terminated with signal 11, Segmentation fault.

Do these fail for everyone because things aren't finished yet or is it just 
me? I'm also having immense difficulties with the new nVIDIA drivers, which 
are supposedly thread safe now. They seem to make things die in random 
places and make a mess of the stack (lots of ?? in backtraces, and ldexp() 
calling itself which really can't happen), and sometimes prevent gdb from 
switching threads. They even make a program linked with libc_r crash, which 
worked fine with the previous driver.

Would it be worth updating to -CURRENT? Otherwise I might have to port to 
Linux which would be rather a pity :) Thanks for any advice,

Lewis
