Hi!
Using the malloc(3X) library, I link with -lmalloc directly after all
the object files, then add in all the other libraries my application
uses including X, Motif. The program is linked by g++ -v, and nothing
untoward is being done with the libraries.
Running the program, malloc() is called successfully many times by my
own code via new, but something else (probably Xt) calls malloc(), and
fails. I get the message
Error: Cannot perform malloc

I know this message is not coming from my own code, because I have my
own operator new() which I single-step over using gdb.

Any clues?

BTW, I am using 3X so that I can call mallinfo(3X) to find the remaining
space on the heap. Is there any other -portable- way of finding out how
much heap memory is left?

Thanks in advance.
