MF 1.7 from the UNIX-TeX distribution fails the trap test on a MIPS b.
I'll give a brief report here, and if some kind soul would like more of the
gory details, I'll give a complete report via mail.
The compiler version:
cc -V reveals that all compiler comonents are:
MIPS cmplrs 2.0 (from RISC/os 4.00)
I compiled with `-signed -systype bsd43'. By default the MIPS compiler does
easy optimizations. I forcibly turned all optimizations off with `-O0' but
it made no difference.
The first (`trapin') phase completed successfully.
The second (`trap') phase bombed.
A summary of the most disturbing things I noticed in my trap run were
the following:
! Too far to shift.
(There's unbounded black in character shipped out!)
! METAFONT capacity exceeded, sorry [main memory size=3001].
The `capacity exceeded' condition occurred only about 10% into the run.
Thanks in advance for your assistance.

But if you actually picked your way through the zillion cc options, you'll for sure come upon the following: -signed Cause all cahr declarations to be "signed char" declarations, the default is to treat them as "unsigned char" declarations. This may or may not cure your problems, but I believe it should relieve the pain of typedef'ing "schar" and change all your "char"s to "schar"s. -- UUCP: {ames,decwrl,prls,pyramid}!mips!rudy (or rudy@mips.com) DDD: 408-991-0247 Rudy Wang (or 408-720-1700, Ext. 247) USPS: MIPS Computer Systems, 930 Arques, Sunnyvale, CA 94086-3650 Quote: I think they're for 1 AM - Descartes, about his midnight snacks
