Failing C source code
This is indeed a target bug. I've attached a C source
code (from the t02.original file) which works OK with -O0
and generates a segfault at -O1:
$ gcc sl2-error.c
$ ./a.out
$ gcc -O1 sl2-error.c
$ ./a.out
Segmentation fault
$ gcc -v
Using built-in specs.
Configured with: ../gcc-4.0-20050123/configure --prefix=/home/zfkts
--enable-languages=c,f95
Thread model: posix
gcc version 4.0.0 20050123 (experimental)
$ gcc -dumpmachine
ia64-unknown-linux-gnu
This is a regression from 3.2.3:
$ /usr/bin/gcc -O3 sl2-error.c && ./a.out
$ /usr/bin/gcc -O1 sl2-error.c && ./a.out
$ /usr/bin/gcc -O0 sl2-error.c && ./a.out
$ /usr/bin/gcc -v
Reading specs from /usr/lib/gcc-lib/ia64-redhat-linux/3.2.3/specs
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man
--infodir=/usr/share/info --enable-shared --enable-threads=posix
--disable-checking --with-system-zlib --enable-__cxa_atexit
--host=ia64-redhat-linux
Thread model: posix
gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-49)
