PR 50892 Latent bug in char pointer assignment

Due to r256284 (PR 78534) there was a latent bug that reared it's head
due to different character length types in the pointer
assignment. Fixed by this patch, which also adds a reduced testcase.

Regtested on x86_64-pc-linux-gnu, committed to trunk as obvious.
