segmentation fault bug

[Felix E. Klee]

Hi,

below is a description of a bug which might be a bug in egcs.

1. I have the following source ("testn.cc"):

     #include <stdio.h>
     #include <math.h>
  
     main()
     {
         float v = fabs(-1.); // A
         printf("a");         // B
         pow(1., 5.);         // C
     }

2. I compile it with "g++ -O testn.cc".
3. When I call "a.out" I get the following error message 
   (this should not happen and therefore seems to be a bug):
   "Segmentation fault"
4. Hardware: AMD K6-2 300 or P90
5. OS: Debian LINUX 2.0 with a 2.0.34 kernel
6. g++ -v:
     Reading specs from /usr/lib/gcc-lib/i486-linux/egcs-2.90.29/specs
     gcc version egcs-2.90.29 980515 (egcs-1.0.3 release)
7. The bug does *not* occur:
     - when I remove either A, B, or C.
     - with gcc version 2.7.2.3.
     - when I copmpile "testn.cc" without the "-O" option.

Do you have any clues if this bug might be my fault, a egcs bug,
or some kind of LINUX bug?

Best Regards,

Felix
