initializes variable that leads to HEAP allocation failure	cdtdoug: iplog+

Description Kirk Beitz

2010-08-07 01:51:54 EDT

in org.eclipse.cdt.debug.edc.tests, resources/Projects/SimpleCpp/inc/Templates.h contains a Template function that has an uninitialized member that can cause a calculation which results in attempting to allocate a *very* large chunk of heap, and will result in a reported HEAP allocation failure.

this probably hasn't been seen previously, because if the memory associated with that variable is 0 (as is probably often the case) or even just small, the failure wouldn't occur, and any testing using this resource would succed.

the attached Templates.h.patch initializes the variable that leads to this problem.
