buffer is created from sal/osl/unx/backtraceapi.cxx with:
70 auto b1 = new void *[maxDepth];
71 int n = backtrace(b1, static_cast<int>(maxDepth));
72 return std::unique_ptr<BacktraceState>(new BacktraceState{ b1, n });
and from sal/osl/w32/backtrace.cxx with:
79 auto pStack = new void *[maxDepth];

81 // "CaptureStackBackTrace function" claims that you "can capture up to
82 // MAXUSHORT frames", and on Windows Server 2003 and Windows XP it even
83 // "must be less than 63", but assume that a too large input value is
84 // clamped internally, instead of resulting in an error:
85 int nFrames = CaptureStackBackTrace( 0, static_cast<ULONG>(maxDepth), pStack, nullptr );

87 return std::unique_ptr<BacktraceState>(new BacktraceState{ pStack, nFrames });
