[gmx-developers] Glibc error in eigio.c when flooding method called and correction

[Oliver Lange]

Dear all,

Thank you Zhi for reporting the bug. I just want to point out for 
clarity, although you said it already:
The patch has to be applied to the gromacs library file for eigenvector 
input-output handling

*eigio.c*: between line 110 and line 111
add
 *eigval=NULL;

do not change
 make_edi.c

Cheers
Oliver
