happened with my previous systems too (not sure anymore but i think it was gcc3.3.3 and 3.4.1) Happens with default qemu default optimization : -Wall -O2 -g -fno-strict-aliasing when setting to -O0 it compiles, but doesnt work (segfaults during runtime) the error during compilation is: target-i386/op.c In file included from /usr/src/emulator/qemu-snapshot-2005-04-18_23/target-i386/op.c:22: /usr/src/emulator/qemu-snapshot-2005-04-18_23/target-i386/exec.h: In function `helper_fldt': /usr/src/emulator/qemu-snapshot-2005-04-18_23/target-i386/exec.h:475: warning: cast to pointer from integer of different size /usr/src/emulator/qemu-snapshot-2005-04-18_23/target-i386/exec.h: In function `helper_fstt': /usr/src/emulator/qemu-snapshot-2005-04-18_23/target-i386/exec.h:480: warning: cast to pointer from integer of different size /usr/src/emulator/qemu-snapshot-2005-04-18_23/target-i386/op.c: In function `op_goto_tb0': /usr/src/emulator/qemu-snapshot-2005-04-18_23/target-i386/op.c:1277: warning: cast to pointer from integer of different size /usr/src/emulator/qemu-snapshot-2005-04-18_23/target-i386/op.c: In function `op_goto_tb1': /usr/src/emulator/qemu-snapshot-2005-04-18_23/target-i386/op.c:1282: warning: cast to pointer from integer of different size /usr/src/emulator/qemu-snapshot-2005-04-18_23/target-i386/op.c: In function `op_divw_AX_T0': /usr/src/emulator/qemu-snapshot-2005-04-18_23/target-i386/op.c:374: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate.
