Thanks, Colin, for providing the fixes+backport and Brian, for including them into the repository.
I hope the following serves at least as a regression test. [Test Cases] 1) ESET NOD32 Antivirus4 4.0.90.0 with /etc/ld.so.preload (which serves to files scanning on access) 1a) man-db 2.8.3-2 and xz-utils 5.2.2-1.3 installed from stable ubuntu 18.04 distribution 1b) man-db 2.8.3-2 installed from bionic-proposed and xz-utils 5.2.2-1.3 installed from stable ubuntu 18.04 distribution 1c) man-db 2.8.3-2 installed from bionic-proposed and xz-utils 5.2.2-1.3 installed from stable ubuntu 18.04 distribution, additionally xz-utils 5.2.4 installed to /usr/local (without package) in all cases 1x) Update of the Manual-DB e.g. by "sudo mandb -c" leads to the error messages: ... /usr/bin/mandb: zcat < /usr/share/man/man1/lz4_decompress.1.gz: Bad system call /usr/bin/mandb: /usr/lib/man-db/manconv -f UTF-8:ISO-8859-1 -t UTF-8//IGNORE -q: Bad system call /usr/bin/mandb: zcat: Bad system call ... For 1b and 1c this was also tested with XZ_DEFAULTS=--threads=0. In all cases 1x) "man mandb" formats correctly. (Maybe that was a problem with earlier ESET versions.) 2) ESET NOD32 Antivirus4 4.0.90.0 without /etc/ld.so.preload 2a) man-db 2.8.3-2 and xz-utils 5.2.2-1.3 installed from stable ubuntu 18.04 distribution 2b) man-db 2.8.3-2 installed from bionic-proposed and xz-utils 5.2.2-1.3 installed from stable ubuntu 18.04 distribution 2c) man-db 2.8.3-2 installed from bionic-proposed and xz-utils 5.2.2-1.3 installed from stable ubuntu 18.04 distribution, additionally xz-utils 5.2.4 installed to /usr/local (without package) all 2x) ok für man-db generation and formatting of man pages System Architecture: i386 Ubuntu 18.04 Kernel Linux pc2 4.15.0-33201808301234-generic #0+mediatree+hauppauge-Ubuntu SMP Thu Aug 30 19:02:06 UTC 2018 i686 i686 i686 GNU/Linu The mandb problem doesn't occur with my 64bit Ubuntu installation, although ESET is installed there as well! Conclusion: The bugfix dosn't resolve my problem, but it doesn't make things worse for me, so if it helps others...
