[Bug rtl-optimization/16490] New: segfault while compiling with -fprofile-use

["kapalka at icslab dot agh dot edu dot pl" <gcc-bugzilla@gcc.gnu.org>]

Good morning,

I was compiling the ROOT v4.00.06a (root.cern.ch) on Itanium 2 platform, Linux
system with -fprofile-generate, I run a few benchmarks and next I tried to
re-compile the package with -fprofile-use. Unfortunately, the compilation
process stopped on the file "build/rmkdepend/parse.c" with the following error:

build/rmkdepend/parse.c: In function `undefine':
build/rmkdepend/parse.c:535: internal compiler error: Segmentation fault

To reproduce the bug, you should use the 2 files I'm enclosing with the bug
report. The command-line causing the error:

gcc -O2 -fprofile-use -fPIC -D_REENTRANT -c parse.i

However, even "gcc -O2 -fprofile-use -c parse.i" when the "parse.gcda" file is
NOT present gives the same error, obviously together with the information "file
parse.gcda not found, execution counts assumed to be zero".

My compiler version:
Reading specs from /opt/gcc3.4.1/lib/gcc/ia64-redhat-linux/3.4.1/specs
Configured with: ./configure --prefix=/opt/gcc3.4.1 --enable-shared
--enable-threads=posix --disable-checking --with-system-zlib
--enable-__cxa_atexit --host=ia64-redhat-linux --enable-languages=c,c++,f77
Thread model: posix
gcc version 3.4.1

Best regards,

Michal Kapalka
