Description andriy 2005-04-18 15:17:31 UTC 
GCC complains (rightly so) on five dereferences that are incorrectly
(unnecessarily) coded in the two files named in the summary.

(1) xmlschemas.cc - around lines 1839 and 1847 
Description: in both lines, the code says:  *end++;
The asterisk is unnecessary, and causes a temporary to be created and discarded.
The intention seems to have been to just increment end, so it should read:  ++end;
(2) xmlregexp.c
Description:  same phenomenon, around lines 2638, 2644 and 2646.
Here, the dereferences should be removed on *valStr++; and *expStr++; and
*valStr+; (again).
Comment 1 kbuchcik 2005-04-19 15:04:20 UTC 
Fixed in CVS. xmlschemas.c (1.132) and xmlregexp.c (1.45).

Thanks for pointing this out!
