Also, UNIX crashes with a panic in the emulator when I run the precompiled gzip or the cc from the 3.51 Development set.
The input to either program does not matter--the crash always occurs as long as there is some input.
This behavior got me thinking that there may be an error in shared memory emulation. As you know, the 3b1 VM system has 512KB dedicated to shared memory, which some programs use, and some do not.
Is it possible that there is a bug in the memory system relating to the shared memory segment? (I am just guessing that cc and gzip make use of it, but something distinguishes these programs from those that do not cause a panic.)
