Hi, I had a look at this. tcsh was hanging inside its custom calloc implementation. This was because GCC 5 now optimizes a malloc, memset sequence into a calloc sequence, but this caused the custom calloc to call itself and enter an infinite loop. One solution would be to rename some of these custom memory implementations. The other easier solution is to disable this optimization using -fno-builtin. This is what I've done in the attached patch. Thanks, James
