hi,

I just try to remove and rebuild and install GROMACS.

This time the self-built one also can not pass the test. The same errors
are reported:

As a general rule, do not do installations and tests of installations as root. This makes it very easy to break your system. One symptom of a broken system is things not working any more. Sound familiar?

If you have a need to install as root, then do the unpack, configure & make (& make test) in your user space as yourself, and then sudo make install. This is just sensible... if someone messes up (the distributor, or more likely you) you'd much rather not be root.

(if test -d "gmxtest"; then cd "gmxtest"; ./gmxtest.pl all; cd ..; \
        else echo "No gmxtest directory found. Please download and
unpack it here.";\
        fi)
*** glibc detected *** mdrun: realloc(): invalid next size: 0x08296ec8

Perhaps the authors can suggest whether gmxtest.pl uses the GROMACS binary from the same source tree, or whichever is pointed to by GMXLIB. If the latter, then you probably still have something broken somewhere.

On the above sudo evidence, I'd actually be tempted to scorched-earth your machine and re-install your OS rather than mess around any more.
