[Bug bootstrap/39011] New: lto bootstrap failure on ppc-linux

[andreast at gcc dot gnu dot org]

Bootstrap breaks while configuring libgcc. Distribution is f10.

Here the conftest.c which fails:

/* confdefs.h.  */

 #define PACKAGE_NAME "GNU C Runtime Library"
 #define PACKAGE_TARNAME "libgcc"
 #define PACKAGE_VERSION "1.0"
 #define PACKAGE_STRING "GNU C Runtime Library 1.0"
 #define PACKAGE_BUGREPORT ""
 /* end confdefs.h.  */

 int
 main ()
 {

   ;
   return 0;
 }


The failure report:

checking for suffix of object files...
configure: error: in
`/share1/devel/gcc-testing/lto/objdir/powerpc-unknown-linux-gnu/libgcc':
configure: error: cannot compute suffix of object files: cannot compile

Compiling the above snippet with:
/share1/devel/gcc-testing/lto/objdir/./gcc/xgcc
-B/share1/devel/gcc-testing/lto/objdir/./gcc/
-B/usr/local/powerpc-unknown-linux-gnu/bin/
-B/usr/local/powerpc-unknown-linux-gnu/lib/ -isystem
/usr/local/powerpc-unknown-linux-gnu/include -isystem
/usr/local/powerpc-unknown-linux-gnu/sys-include -c -g -O2    conftest.c

ends with:

conftest.c:16: internal compiler error: Segmentation fault

Leaving the -g away or add -gstabs lets the compiler build the .o file.

Here the bt from gdb:
