Subject: Re:  gprof reads executable 10x slower on opteron/x86_64

No.

Just g++ -O3 -gp to compile and just gprof on the executable and
gmon.out. The executable is 100Mb large.

Adding stab debug info in place of dwarf2 makes it run fast. Running in
GDB with dwarf debug I see it not using the "dwarf" named functions to
retrieve info.

Ah, yes, it does seem as if the type_info table is stored in reverse order and
accessed from the end.  In that case increasing alignment padding should work.

Already fixed in CVS source, but thanks for the report.
