Setting SAGE_CHECK=yes just means that after building the pari
library, the self-test routines are also run. It does not affect Sage
after the new spkg is installed.

This still caused a segfault for me in dmesg while doctests pass.

This depends on the setting of LD_LIBRARY_FLAG. If you do the same
within "sage -sh" you should get the correct library.

After doing that the doctest still passes, and I still get

[8562085.592129] gp[1128] trap invalid opcode ip:7f7f003b5be7

Very strange that these errors do not result in a failing doctest...
John, Jan:
On the failing machines, could you install the PARI spkg with checking
enabled? i.e. please do
env SAGE_CHECK=yes ./sage -f
http://sage.math.washington.edu/home/release/sage-4.6.alpha3/sage-4.6.alpha3/spkg/standard
On two different 64-bit ubuntu machines:
1 works fine:

Hi
As I've had one external confirmation, more than one
sage version, and several laptops here, I'll continue to think
about this.
Looking for libpari-gmp.so, I found these:
r...@capepoint:/usr/local/src/sage-4.5.3/local/lib#ls -l libpari*
-rwxr-xr-x 1 root root 3160120 Oct 11 17:06 libpari-gmp
Also, I can NOT reproduce the segfault on the following system with
sage-4.6.alpha3:
$ Linux arcanis 2.6.32-gentoo-r7 #5 SMP Thu Jun 10 23:07:26 CEST 2010
