I think you've touched upon a common ailment for all software 
deployables..exhausting resources
There have been a few ideas kicked around..most notably


check if requested_allocation <=available_heap
the problem is determining available heap varies with each OS and ARCH type so..

a comprehensive testcase matrix would need to incorporate every OS/ARCH 
permutation 

if this is important to you file a JIRA and submit a patch (with appropriate 
testcases)

and as long as you can prove that all testcases pass ..I am sure the patch will 
be approved


https://issues.apache.org/jira/browse/AXIS2C


Looking forward to seeing your patch

 

Thanks,
Martin Gainty

> Hi.

> We are using version 1.6.2 of the Axis2/Java framework to generate C
> code for use with Axis2/C, from some WSDL service descriptions. We have
> noticed that the generated code does not always check the return value
> of memory allocations, and there is therefore a risk of null pointer
> de-references in low memory situations.
> 
> For example :
> 
> p_prefix = (axis2_char_t*)AXIS2_MALLOC(env->allocator, sizeof
> (axis2_char_t) * ADB_DEFAULT_NAMESPACE_PREFIX_LIMIT);
> sprintf(p_prefix, "n%d", (*next_ns_index)++);
> 
> It seems to be generally related to allocations before a call to
> sprintf. Other times the return value is checked :
> 
> _AuthResponse = (adb_AuthResponse_t *) AXIS2_MALLOC(env->allocator,
> sizeof(adb_AuthResponse_t));
> if(NULL == _AuthResponse)
> {
> AXIS2_ERROR_SET(env->error, AXIS2_ERROR_NO_MEMORY, AXIS2_FAILURE);
> return NULL;
> }
>

> We are certainly willing to patch this and submit back the code, but
> before embarking on this effort I'd like to validate this with the
> list. Is this something that would be accepted, and any hints at the
> best way to tackle this would be much appreciated.
