[issue3070] Wrong size calculation in posix_execve

[Adam Olsen]

New submission from Adam Olsen <rhamph at gmail.com>:

In 2.x, the size of C string needed for an environment variable used by
posix_execve was calculated using PyString_GetSize.  In 3.0 this is
translated to PyUnicode_GetSize.  However, in 3.0 the C string is the
UTF-8 encoded version of the unicode object, which doesn't necessarily
have the same length as what PyUnicode_GetSize reports.

The simplest solution I see is to use strlen() instead.
