Is there a problem using malloc and new together?

[sapird]

Hi,
I try to solve a problem in a C++ code I did not write:
When I run the application I get a memory problem, and the message says that memory was allocated with new and ran over with malloc.
Is this really the problem, or is it a simptom for something else?
Is there a known problem with using new and malloc in the same application?
Another note: the problem appears only when compiled with debug information.
The application runs under OS/2 operating system.

The relevant parts of the code:

void *d_area;
int dsize=10;
d_area = malloc (dsize);
--------
char *penv = getenv ("xxxx");
char *grp;
grp = new char (sizeof (penv) + 1);

Please note that this is only the suspected lines, and the statement int dsize=10; and similar are only shown here for understanding the inportant lines (new and malloc)

Thanks.
