Fixed in https://bitbucket.org/tmidas/midas/commits/e2c4871026121ed1cc44a69b9e3e2d428a6c84d1

For the record, I am stumped by this problem. We have definitely ruled out any data overflow inside the midas message code (there are no
long messages sent). My only guess is that the frontend itself is corrupting the midas message buffer, but this corruption
must be unlikely lucky to corrupt just the "_" character (and maybe what follows it) from the "MSG_" header inside the buffer.
