gcc version pgcc-2.91.66 19990314 (egcs-1.1.2 release)
i686-pc-linux-gnu
glibc-2.0.7(RH5.2)

My program is OK with pgcc -O6, but with -pg it segfaults if
optimization is -O6.  It's OK with -pg with -O3.

If -pg -O6 is used it says:

g++ -g -W -O6 -ffast-math -malign-double -pg -c -o TestEqualizer2.pg.o TestEqualizer2.cc
TestEqualizer2.cc: In function `int main(int, char **)':
