the exact version of GCC is 4.1.1
the system type is sparc-sun-solaris2.8
the options given when GCC was configured/built:
--prefix=/tmp/local/unixutil/gcc-4.1.1
--with-local-prefix=/usr/local/myCompanyName
("myCompanyName" is not the exact wording)
(also, there is a symlink /tmp/local/unixutil/gcc -> gcc-4.1.1)
the complete command line that triggers the bug:
gcc -Wall -o foo.o -c foo.cc
the compiler output (error messages, warnings, etc.):
stdout: nothing
stderr:
gcc: Internal error: Segmentation Fault (program cc1plus)
Please submit a full bug report.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
foo.o: not created
the preprocessed file:
see below; for ease of transmission, the full source is not given;
to have it, replace the ZZZZZ by the missing 65524 values (in
increasing order)
additional remarks:
1) if the file is renamed foo.c (the C language is triggered instead
of C++), the bug does not show up
2) if the command is installed in a Makefile:
---Makefile--------------------------
all:
/tmp/local/unixutil/gcc/bin/gcc -Wall -o foo.o -c foo.cc
-------------------------------------
then the bug does not show up if the GNU make is used, however the bug
still shows up if the /usr/ccs/bin/make is used
---foo.ii----------------------------
# 1 "foo.cc"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "foo.cc"
void myfunction(unsigned short localChar) {
switch (localChar) {
case 0:
case 1:
case 2:
case 3:
case 4:
case 5:
ZZZZZ
case 65530:
case 65531:
case 65532:
case 65533:
case 65534:
case 65535:
break;
};
return;
};
