According to the gettext manual:
The gettext function does not modify the value of the global errno
variable. This is necessary to make it possible to write something
like:
printf (gettext ("Operation failed: %m\n"));
Here the errno value is used in the printf function while processing
the %m format element and if the gettext function would change this
value (it is called before printf is called) we would get a wrong
message.

I don't think this example is valid. You only return from malloc, and do
not reset errno.
Did you experienced something like that without gdb?
