Andrew,
BTW, if I only use the printf("act_handler sig %d addr=%p base=%p end=%p\n",
sig, add, &alt_stack[0], alt_top);
There is no SIGSEGV during execution.
So, I don't believe it a hard rule the printf is not allowed in signal
handlers.

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Is calling
printf a valid thing to do inside this signal handler?
Also can you try a newer compiler 4.4.7 is no longer supported. Since you are
using a redhat supplied GCC, you really should reporting it to them.
