From Bugzilla Helper: User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.4.2 i586) I am using gcc-2.96-79 (+all related packages) on a RH 7.0 system (glibc-2.2-5) and try to compile the gnustep-gui-0.6.7 package (obtained from www.gnustep.org). The compilation exits with an internal compiler error while processing the NSPanel.m file. Reproducible: Always Steps to Reproduce: 1.get, rebuild and install ftp://ftp.gnustep.org/pub/gnustep/rpms/srpms/gnustep-make-0.9.2-1.src.rpm 2. get, rebuild and install ftp://ftp.gnustep.org/pub/gnustep/rpms/srpms/gnustep-base-0.9.3-1.src.rpm 3. get ftp://ftp.gnustep.org/pub/gnustep/rpms/srpms/gnustep-gui-0.6.7-1.src.rpm 4. rpm --rebuild gnustep-gui-0.6.7-1.src.rpm Actual Results: the compilation continued until a certain file (NSPanel.m) was reached. At that point it stopped with an internal compiler error. Expected Results: Compile to the end! This is the command line that called the gcc and the error message: gcc NSPanel.m -c -DGNUSTEP_INSTALL_LIBDIR=\"/usr/GNUstep/System//Libraries\" -DGNUSTEP_INSTALL_PREFIX=/usr/GNUstep/System/ -DGNUSTEP_TARGET_DIR=\"ix86/linux-gnu\" -DGNUSTEP_TARGET_CPU=\"ix86\" -DGNUSTEP_TARGET_OS=\"linux-gnu\" -DLIBRARY_COMBO=\"gnu-gnu-gnu-xgps\" -DGNUSTEP -DGNUSTEP_VERSION= -DGNUSTEP_MAJOR_VERSION= -DGNUSTEP_MINOR_VERSION= -DGNUSTEP_BASE_LIBRARY=1 -DGNU_GUI_LIBRARY=1 -DGNU_RUNTIME=1 -DGNUSTEP_BASE_LIBRARY=1 -D_REENTRANT -fPIC -DGSWARN -O2 -march=i586 -Wno-import -fgnu-runtime -Wall -I../Headers -I. -I/usr/GNUstep/System/Headers -I/usr/GNUstep/System/Headers -I/root/GNUstep/Library/Headers -I/usr/GNUstep/Local/Library/Headers -I/usr/GNUstep/Network/Library/Headers -I/usr/GNUstep/System//Library/Headers -I/usr/GNUstep/Network/Headers/gnustep -I/root/GNUstep/Headers/gnustep -I/usr/GNUstep/Local/Headers/gnustep -I/usr/GNUstep/System//Headers/gnustep -I/usr/GNUstep/Network/Headers/ix86/linux-gnu -I/root/GNUstep/Headers/ix86/linux-gnu -I/usr/GNUstep/Local/Headers/ix86/linux-gnu -I/usr/GNUstep/System//Headers/ix86/linux-gnu -I/root/GNUstep/Headers -I/usr/GNUstep/Local/Headers -I/usr/GNUstep/Network/Headers -I/usr/GNUstep/System//Headers -o shared_obj/ix86/linux-gnu/gnu-gnu-gnu-xgps/NSPanel.o In file included from ../Headers/AppKit/GMAppKit.h:29, from NSPanel.m:53: ../Headers/AppKit/AppKit.h:170:8: warning: extra tokens at end of #endif directive NSPanel.m: In function `-[GSAlertPanel sizePanelToFit]': NSPanel.m:830: Internal compiler error in validate_replace_rtx_1, at recog.c:561 Please submit a full bug report.

Created attachment 13383 [details] NSPanel.mi is created with -v flags -save-temps
A SUBREG_BYTE related bug. Simplified into: float d; int e, f; void foo (void) { struct { float u, v; } a = {0.0, 0.0}; float b; int c; c = e; if (c == 0) c = f; b = d; if (a.v < b) a.v = b; } at -O, -O2, have just fixed this and the fix will appear in gcc-2.96-80.
