rpmbuild ends in error 'getOutputFrom(): Broken pipe' under redhat 9

cloning sometimes results in "System error: no child" remark, but I can't replicate it

biosdisk read operations returned wrong values in programs using
this interface (both my program and explore2fs).
This bug wasn't present on previous occasions. It now emerges
when you searched for a word at the harddisk. If during this long
search you start explore2fs it doesn't work also not after  you interrrupt
this search.  Other beds also don't work. The is behevior stops
after you terminate the trouble making program.
After a little (unrelated) modification in my biosdisk32 the problem
was not longer present.
