The generated function update_multiple_arg() calls realloc several times, but does not check the result of the allocation nor does correctly free the original data in case of failure.

This was initially noticed in OpenSC generated code:

https://github.com/OpenSC/OpenSC/blob/83b188c950bce3846b09e7b8676c46080e239e91/src/tools/npa-tool-cmdline.c#L1688

Checking the current source shows there is nothing changed.
