[svn-r19892] Purpose:
Bug 2089 - GMQS: h5diff segfault on a compound dataset with fixed length +
vlen string type order
Description:
This is fix for the segfault when h5diff compares a compound dataset with
combination of fixed length string types and vlen string types in certain
orders. Optimized vlariable length string handling codes. The fix is
referred from h5dump handling vlen strings.
For testing, several compound datasets were added with various combinations.
Previous failed cases:
- Vlen string, Fixed length string, Vlen string, Fixed length string
- Fixed length string, Fixed length string, Vlen string, Vlen string
- Fixed length string, Vlen string, Fixed length string, Vlen string
Tested:
jam (linux32-LE), amani (linux64-LE), heiwa (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE)
