New submission from Alexey Izbyshev <izbyshev at ispras.ru>:
The return value of PyFloat_FromDouble() at https://github.com/python/cpython/blob/48ce4897f8f8d91d948ecd1241ffab002df2be9e/Python/bltinmodule.c#L2403 is not checked for NULL and then dereferenced.
Reported by Svace static analyzer.
A similar issue in an 'if' statement above was fixed in #18560. Note that 2.7 is affected by both issues, so I can fix both if needed.
