What output do you get from gmxcheck -f martin_md_290K_100ns_tau1.xtc ? Also,
can you extract that problematic frame with trjconv and run g_density on that
one frame (what happens?). Also, can you make a new .xtc that is missing that
last frame and see what g_density does?
These will help you to figure out what is going on.

Hi All
I have a 100 ns lipid simulation for which I want the density profile. I issued
the following command
g_density -f martin_md_290K_100ns_tau1.xtc -n dppc.ndx -s
martin_md_290K_100ns_tau1.tpr -o water_density.xvg -b 50000
The program fails with the following message
Selected 3: 'Water'
Last frame 25000 time 100000.000
*** glibc detected *** g_density: munmap_chunk(): invalid pointer:
