[PATCH 0/1] MR9335: crypt32/tests: Add null character to avoid buffer overrun (ASan).

[Bernhard Übelacker]

These tests give intentionally ascii strings to unicode expecting
functions. Therefore add these null characters to make them appear
terminated to unicode functions.

[ASan report details](https://gitlab.winehq.org/bernhardu/wine/-/blob/asan-pe_2025-10-18_wine-10.1...)
