switching from HDF5 to HDF5BS got an error on memory freeing : free() invalid pointer
Here some traces I get using gdb. On ubuntu if you want toget gdb attached to a process, you must change the sysctl parameter: sysctl kernel.yama.ptrace_scope=0 or for a permanent setting copy the /etc/sysctl.d/10-ptrace.conf to a /etc/sysctl.d/50-ptrace.conf and change the value to 1. At next reboot the parameter ptrace_scope will be set to 0.
