Description Holger Hoffstätte 2014-04-10 19:48:53 UTC

After upgrading to gawk-4.1.1 makewhatis starts to spew errors:

...
bzcat: I/O or other error, bailing out.  Possible reason follows.
bzcat: Broken pipe
	Input file = /usr/share/man/man1/./git-log.1.bz2, output file = (stdout)

bzcat: I/O or other error, bailing out.  Possible reason follows.
bzcat: Broken pipe
	Input file = /usr/share/man/man1/./git-diff-tree.1.bz2, output file = (stdout)
...

There is nothing wrong with the man pages in question; manually calling bzcat on them prints their contents without problems. Investigation yielded that makewhatis pipes the compressor used by a man page into a giant awk script, and that seems to fail now. Reverting to gawk-4.1.0 immediately resolved the problem.


Reproducible: Always

Steps to Reproduce:
1. update to gawk-4.1.1
2. run makewhatis
3. errors galore!

Actual Results:  
See description.

Expected Results:  
A silently processed whatis database.

This bug is independent of USE/CFLAGS and can be reproduced with a vanilla build of the gawk executable.
