[svn-r24112] Description:
Bring r24101 & 24111 from trunk to 1.8 branch:
r24101:
=======
Description:
Clean up warnings, enable new compiler warning flag(s) and bring back
changes from Coverity branch:
r20813:
Remove the dead code as listed for coverity bug #1722. h5committested.
r20814:
Issue 69: Check return value and throw error if negative return. Also free datatype id on error
r20815:
Use HDstrncpy. --gh
r20816:
Replaced one last HDstrcat call with HDstrncat to resolve coverity issue 832.
r20817:
Use HDstrncpy and HDstrncat. --gh
r20818:
Purpose: Fix valgrind issues with h5jam
Description:
Modified h5jam to free strings strdup'd in parse_command_line before exit. Note
that they may still not be freed in case of error, due to the widespread use of
exit().
r20819:
Issue 80: change loop to use int as loop index.
r20820:
Maintenance: Fixed the bug found by coverity CID 788
There were two problems with this function:
1) it tried to unnecessary free NULL pointer
2) it tried to allocate c_name buffer that is done by H5Pget_class_name
r24111:
=======
Description:
Restrict GCC diagnostic pragmas to only gcc 4.6+
Tested on:
Mac OSX 10.8.4 (amazon) w/gcc 4.8.1, C++ & FORTRAN
(too minor to require h5committest)
