>Description:
[ Reported to the Debian BTS as report #177016.
Please CC 177016@bugs.debian.org on replies.
Log of report can be found at http://bugs.debian.org/177016 ]
Regression compared to gcc-2.95.3 and gcc-3.0.4. Compiling the example
(attaching in a followup):
$ gcc -c -O1 -fPIC bug-177016.i
foo.c: In function `H5F_istore_read':
foo.c:281: warning: assignment makes pointer from integer without a cast
foo.c:307: Internal compiler error in instantiate_virtual_regs_1, at function.c:4134
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
changing the optimization to -O0 or -O2 lets the compilation succeed.
