-
- Hmmm .. MiNT just doesn't like me these days. I'm wondering if I still
- have the patched 1.09 that I was using before since the patched 1.10 is
- the pits.
-
- I now have programs crashing and giving a BUS ERROR @ PC=7F4 right after
- an Exception 10. This is insane since I know the program doesn't
- use any LineA calls at all!! <<Unless MiNTLIB uses some>> I wrote this
- so I KNOW it doesn't call LineA, or VDI, or GEM, or anything else.
- It dies right on start-up, but ONLY if I use ^C to kill fsck. If fsck
- dies early I get Exception 10 and then a BUS ERROR on some programs.
- What does FSCK have to do with LineA ?? Or am I reading this wrong?
- When MiNT says exception 10, does it mean exception 16 (is it in hex?)
-
- Also, I think the Mintlib's system() call is screwed up. My entire
- system locks up when I execute it, and I've used gdb to make sure that
- it was system (the command line passed seems to run but then the whole
- system crashes). System() gets to _realloc() according to gdb.
-
- BTW, this was the first time gdb worked for me and showed the source
- lines and such. I'm not sure why it refused to work when debugging
- TOSWIN (must have something to do with GEM).
-
- Oh ... TOSWIN loses less RAM when I use WINX. I don't remember exactly
- how much less, but it isn't much, but its finally something different.
- My guess is that TOSWIN may have some bad pointer math that overwrites
- some info at the beginning of the memory block (that MiNT uses to tag the
- block of RAM) thus making MiNT think pid 0 (MiNT itself) is the owner.
- Is this a possibility? I was thinking that maybe memory protection may
- not catch this either since the application does own the block. Right?
-
- Anyway, I'm gonna start flipping through TOSWIN's source hoping to find
- this as I don't have any other place to look. As to LineA and some of the
- weird crashes and lock-ups that I've been getting with MiNT lately, I
- hope someone here looks into these (its above me head, well, most of it
- is, well, some of it, I just haven't looked at the source enough to know
- it as well as some of you I guess). As to system() crashing my system(),
- hmm ... bad pun wasn't it? I'll look at that too since I'll need to fix
- that one ASAP (or find another way for my terminal to run external commands).
