[gmx-developers] Bug in gmx_wham

[Béla Voß]

Hello,

the read_pdo_data() and read_pull_xf() functions in gmx_wham.cpp
internally convert timestamps to femtoseconds. When reading long data
files, this can lead to integer overflows due to a static cast to int.
(microseconds are not the future anymore)

To fix this (for now), I recommend casting to a 64bit integer, as
suggested in the attached patch file.

Best
Béla
