Here's another crash, on a FRESHLY installed non virtual machine (Ubuntu 12.04), t38modem compiled from scratch from your sources, opal 3.10.3 ptlib 2.10.3, spandsp 0.6.6, this time using TCP transport. Apparently this can be (almost) constantly reproduced by sending a fax from two t38 devices on the same process. Errata, I tried now sending from a process and receiving on a second and the receiver crashed anyway.
