Pete Johns 6a52538a9a Fixed #1949: assert() hides memory leaks
Added separate unit-test (trac1949), initially broken to highlight the error and added "assert" to call_func_white_list.

Left TestMemleakInFunction::call_func() as is, as this wouldn't highlight the actual problem.

Kimmo Varis 6db365e6f7 Improve path name handling in ErrorLogger.
This commit adds setfile() method to FileLocation class. The setfile
method converts in Windows path separators to internally used Unix
separators. And getfile() converts path separators back to Windows
separators. This fixes bugs that error reports had mixed path
separators in paths.
