Memory allocation when throwing an exception.

[misra cpp]

MISRA rules only apply to source code, not the binary. So any allocation of memory 'behind the scenes' by the compiler, without the explicit use of new or malloc in the source, doesn't violate the 'no dynamic memory' requirement.

However, it would be prudent to consider the suitability of the compiler's runtime system, e.g. whether the system may run out of memory whilst throwing the exception
