seg fault in H5T.c

John Knutson-2
I'm in the process of migrating from Solaris x86 to RHEL7 and am having
issues reading (on RHEL) one particular data set that was written on the
Solaris platform.  The Solaris HDF5 release is 1.8.9, and RHEL is
1.8.12.  I have not tried newer versions of HDF5 as 1.8.12 is what RHEL
pre-packages and I'd prefer not to have to do manual builds.

The debugger says:
Program received signal SIGSEGV, Segmentation fault.
0x00007ffff5a1a81c in H5T_cmp (dt1=0x6cccc0, dt2=0x7cc9c0, superset=0)
     at ../../src/H5T.c:3948
3948        if(dt1->shared->type < dt2->shared->type)
(gdb) print dt1
$1 = (const H5T_t *) 0x6cccc0
(gdb) print dt1->shared
$2 = (H5T_shared_t *) 0x6ccd30
(gdb) print dt1->shared->type
$3 = H5T_ENUM
(gdb) print dt2
$4 = (const H5T_t *) 0x7cc9c0
(gdb) print dt2->shared
$5 = (H5T_shared_t *) 0x100014d98
(gdb) print dt2->shared->type
Cannot access memory at address 0x100014da4

(gdb) where

The same file can be processed without incident with the same
application on Solaris.  The dataset in question is being created using
the high level tables API and a compound data type.  I can provide a
trace file or other debugging information to help resolve this issue.  
It didn't seem like a good idea to post files to the mailing list.

Any help would be appreciated.
