Hello, Yes, I have now built guile more than a dozen times. And I have just doublechecked again, comparing builds of http://snapshot.debian.org/archive/debian/20141008T040958Z/pool/main/g/guile-2.0/guile-2.0_2.0.11%2B1-9.dsc and http://snapshot.debian.org/archive/debian/20150906T035304Z/pool/main/g/guile-2.0/guile-2.0_2.0.11%2B1-10.dsc : buildlog.guile-2.0_2.0.11+1-9_amd64: make[1]: Leaving directory '/tmp/GUILE/guile-2.0-2.0.11+1-9' dh_auto_build -O--parallel make -j5 make[1]: Entering directory '/tmp/GUILE/guile-2.0-2.0.11+1-9' make -C libguile scmconfig.h make[2]: Entering directory '/tmp/GUILE/guile-2.0-2.0.11+1-9/libguile' \ if [ "no" = "yes" ]; then \ gcc -DHAVE_CONFIG_H -I.. \ -c -o gen-scmconfig.o gen-scmconfig.c; \ else \ gcc -DHAVE_CONFIG_H -DBUILDING_LIBGUILE=1 -I.. -I.. -I../lib -I../lib -I/tmp/GUILE/guile-2.0-2.0.11+1-9 -Wdate-time -D_FORTIFY_SOURCE=2 -Wall -Wmissing-prototypes -Wdeclaration-after-statement -Wpointer-arith -Wswitch-enum -fno-strict-aliasing -fwrapv -fvisibility=hidden -DPACKAGE_PACKAGER='"Debian"' -DPACKAGE_PACKAGER_VERSION='"2.0.11-deb+1-9"' -DPACKAGE_PACKAGER_BUG_REPORTS='"http://www.debian.org/Bugs/Reporting";' -c -o gen-scmconfig.o gen-scmconfig.c; \ fi \ buildlog.guile-2.0_2.0.11+1-10_amd64 dh_auto_build -O--parallel make -j5 make[1]: Entering directory '/tmp/GUILE/guile-2.0-2.0.11+1-10' make -C libguile scmconfig.h make[2]: Entering directory '/tmp/GUILE/guile-2.0-2.0.11+1-10/libguile' \ if [ "no" = "yes" ]; then \ gcc -DHAVE_CONFIG_H -I.. \ -c -o gen-scmconfig.o gen-scmconfig.c; \ else \ gcc -DHAVE_CONFIG_H -DBUILDING_LIBGUILE=1 -I.. -I.. -I../lib -I../lib -I/tmp/GUILE/guile-2.0-2.0.11+1-10 -Wdate-time -D_FORTIFY_SOURCE=2 -Wall -Wmissing-prototypes -Wdeclaration-after-statement -Wpointer-arith -Wswitch-enum -fno-strict-aliasing -fwrapv -fvisibility=hidden -g -O2 -fstack-protector-strong -Wformat -Werror=format-security -DPACKAGE_PACKAGER='"Debian"' -DPACKAGE_PACKAGER_VERSION='"2.0.11-deb+1-10"' -DPACKAGE_PACKAGER_BUG_REPORTS='"http://www.debian.org/Bugs/Reporting";' -c -o gen-scmconfig.o gen-scmconfig.c; \ fi As you can see the former has no -Ox option, the latter has -O2. The old debian/rules was buggy. Downgrade guile to 2.0.11+1-9 from snapshots and the issue goes away. cu Andreas -- `What a good friend you are to him, Dr. Maturin.
