Some additional information. This seems to be a very tricky issue. I can reliably reproduce it when I run debuild as normal user (using fakeroot), for example with a loop in debian/rules running dh_installdocs:
cnt=1; while :; do echo $cnt; dh_installdocs || echo "Error"; cnt=$((cnt + 1)); done 1 2 dh_installdocs: command returned error code 11 Error 3 dh_installdocs: command returned error code 11 Error 4 5 6 7 dh_installdocs: command returned error code 11 Error 8 However, if I run debuild as root or using sudo, the segfault no longer occurs. But I can also not reproduce the error by just running the failing install command directly with fakeroot. The following produces no errors: while :; do fakeroot install -g 0 -o 0 -m 644 -p debian/copyright \ debian/qcontrol/usr/share/doc/qcontrol/copyright || \ echo $?; done The backtrace was created by modifying dh_installdocs to run 'install' inside gdb. Installing libc6-dbg did not result in a more usable backtrace. If needed I can provide access to the box that shows the failures.
