Hello,
The name of the function used to allocate some memory in the inferior is
currently hard-coded to "malloc" in valops.c:
struct value *
value_allocate_space_in_inferior (int len)
{
struct value *blocklen;
struct value *val = find_function_in_inferior ("malloc");
^^^^^^
Unfortunately, on interix, the malloc function is not always there.
Quoting Donn Terry:
<<
malloc() won't necessarily be present; the way our namespace pollution
prevention stuff works, if the user application doesn't call an entry
point at all, it just won't be there. However, _malloc is always
present (at least in any real program) because it's called from within
the library.

May I suggest a new architecture method called for instance
NAME_OF_MALLOC or MALLOC_FUNCTION_NAME? The default would be to return
"malloc", but we could then change it to "_malloc" for the interix
target.
