Create a test allocator that records stack traces for allocations.
Declared in <balst_stacktracetestallocator.h>
explicit
StackTraceTestAllocator(bslma::Allocator* basicAllocator = 0);Optionally specify numRecordedFrames, the number of stack trace frame pointers to be saved for every allocation. Specifying a larger value of numRecordedFrames means that stack traces, when given, will be more complete, but will also mean that both more CPU time and more memory per allocation will be consumed. If numRecordedFrames is not specified, a value of 12 will be assumed. Optionally specify basicAllocator, the allocator from which memory will be provided. If basicAllocator is 0, the MallocFreeAllocator singleton is used. Associate bsl::cerr with this object for error diagnostic output, which may be changed by calling the setOstream manipulator. Set the demanglingPreferringFlag attribute to true, which may be changed using the setDemanglingPreferredFlag manipulator. The behavior is undefined if numRecordedFrames < 2.
