-CURRENT crashes on compilling

[Tarc]

Please, help!
I change my old computer to a new one (see dmesgs links below) and my computer begins to crash anywhere(cc1, sh, awk, ...) with (mainly page fault) very often.

What happines? hardware is ok, I have tested it.
all configuration stay same, 
CFLAGS and COPTFLAGS are "-O2 -pipe"
kernel config: http://tarc.po.cs.msu.su/usr/tarc/kernels/TarcCurrent
old dmesg: http://tarc.po.cs.msu.su/usr/tarc/kernels/dmesg
current dmesg: http://tarc.po.cu.msu.su/tarc/kernels/current/dmesg
