First of all thanks to the people (esp. Klaus Weide) who helped us to 
get FLASH 3 compiling under Solaris.

We are now having problems getting FLASH running in AMR mode. Running 
in single processor mode the dbx output is:

[1] t_delete(0x4a63974, 0x4a63978, 0xffffffffffffffff, 0x0, 0x0, 
0xfffffd7ffb3e8b80), at 0xfffffd7ffb3601e3
   [2] realfree(0x0, 0x0, 0x0, 0x0, 0x0, 0x0), at 0xfffffd7ffb35fe03
   [3] cleanfree(0x0, 0x0, 0x0, 0x0, 0x0, 0x0), at 0xfffffd7ffb3604cf
   [4] _malloc_unlocked(0x0, 0x0, 0x0, 0x0, 0x0, 0x0), at 0xfffffd7ffb35f769
   [5] malloc(0x0, 0x0, 0x0, 0x0, 0x0, 0x0), at 0xfffffd7ffb35f6cd

   [13] MAIN(), line 40 in "Flash.F90"


Flash is trying to do a malloc with parameters all set to 0. We are 
using the standard flash.par that comes with the 3.0 distribution. We 
also have similar problems with the Sod test.

We get similar errors running in multiprocessor mode (e.g. np=2 or 4).

When we run FLASH in Uniform Grid mode, it runs successfully.

The computer is an 8 processor SUN with AMD processors running Solaris 5.10

Thanks,
Geoff Bicknell
