Title:
  g++ 4.5 internal compiler error when compiling adplug-2.2.1

Status in “gcc-defaults” package in Ubuntu:
  Incomplete

Bug description:
  I've downloaded adplug-2.2.1.tar.bz2 from here: http://sourceforge.net/projects/adplug/files/AdPlug%20core%20library/
  I've tried to compile it (Ubuntu natty, x86 32 bit). However I've got internal compiler errors, like this one:

  lgb at vega:~/src/adplug-2.2.1/src$ g++ -DPACKAGE_NAME=\"adplug\" -DPACKAGE_TARNAME=\"adplug\" -DPACKAGE_VERSION=\"2.2.1\" "-DPACKAGE_STRING=\"adplug 2.2.1\"" -DPACKAGE_BUGREPORT=\"\" -DPACKAGE_URL=\"\" -DPACKAGE=\"adplug\" -DVERSION=\"2.2.1\" -DSTDC_HEADERS=1 -DHAVE_SYS_TYPES_H=1 -DHAVE_SYS_STAT_H=1 -DHAVE_STDLIB_H=1 -DHAVE_STRING_H=1 -DHAVE_MEMORY_H=1 -DHAVE_STRINGS_H=1 -DHAVE_INTTYPES_H=1 -DHAVE_STDINT_H=1 -DHAVE_UNISTD_H=1 -DHAVE_DLFCN_H=1 -DLT_OBJDIR=\".libs/\" -DHAVE_LIBSTDC__=1 -DHAVE_GETOPT_H=1 -I. -Dstricmp=strcasecmp -I/usr/include/libbinio -mtune=pentium4 -march=pentium4 -g -O2 -MT protrack.lo -MD -MP -MF .deps/protrack.Tpo -c protrack.cpp  -fPIC -DPIC -o .libs/protrack.o

  Please submit a full bug report,
  with preprocessed source if appropriate.
  See <file:///usr/share/doc/gcc-4.5/README.Bugs> for instructions.

  I don't think it's an ANSI standard problem (as the README.Bugs
  suggests) as it compiles if I change -O2 to -O0.
