| Doc Text: |
The ncompress utility previously relied on the glibc implementation of the memcpy() function. A recent glibc update optimized memcpy(), which resulted in data corruption in ncompress file compression and decompression. This update replaces memcpy() with the memmove() function and ncompress now works as expected.
