I had exactly the same problem. It disappeared when I recompiled
patch using the new libraries (strange indeed).

However, i still have some problems with 1.5:
 - The strncpy() routine doesn't seem to work all the time.
   Someone told me that there was a patch for it, could some-
   body re-post it please?
 - I get lots of ".. panic Exit via trap 6" at irregular intervals.
   I couldn't reproduce the exact circumstances, but they keep
   appearing during compilation, listing files etc. This is still
   under Minix 1.1, so maybe it will get better with 1.5
 - Compiling the kernel, mm & fs results in many warnings about
   pointers (conversion to integer loses accuracy, conversion
   to long.., incompatible pointers in =, etc). Is this because
   the PC 1.5 assumes that pointer=integer=long? I ignored the
   warnings, but I don't like them at all.

Has anybody succeeded in installing the new 1.5 on his ST, with-
out cross-compiling from GNU-C or other "tricks"?
It is DEFINITELY NOT possible to patch an ORIGINAL 1.1 Version
directly to 1.5: not only programs like sed are missing in the
1.1 package, but it is also necessary to include some of the new
library routines in order to compile the new programs.

I have managed to compile a 1.5 minix.img using just the standard
minix compiler and the new libraries, but it doesn't work very
well... I get a nice "Memory Fault - Core dumped" as soon as
I log in, and "ls" results in another core dump... well, at
least "rm core" works ;-)
I guess that the old strncpy() is to blame, but there seem to
be lots of other bugs left. I wonder how many fixes will be needed
before 1.5 runs smoothly - has anyone kept track of all the postings
that dealt with bug fixes? Since most of them aren't "official"
anyway, i am afraid that there are 1001 different versions
of 1.5 (and this doesn't make updates easier).

Keep patching,    Stefan
