[issue2238] TypeError instead of SyntaxError for syntactically invalid gen exp

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc added the comment:

Interestingly, in debug mode, the message "XXX undetected error" is
printed to stderr.
And this gives the solution: in ast.c, some calls did not check the
return status.

Committed revision 61240, will backport to 2.5.
Thanks for the report!
