gdb crashes with Solaris 10 x86

[Richard Walter]

I have to debug a network gateway program with gdb 6.3.50.20051108. When
the network connection is started the program gets a segmentation fault.
When i run the program with gdb, the gdb crashes. 
The program is compiled with gcc 3.4.3.
gdb 6.2.1 and 6.3 have the same problem.

Output from program running with gdb:
--pointer agatename=810426c
Segmentation Fault (core dumped)


Output from the program running with solaris truss:
write(1, " t _ l i s t e n   c o m".., 49)      = 49
--pointer agatename=810426c
write(1, " - - p o i n t e r   a g".., 28)      = 28
    Incurred fault #6, FLTBOUNDS  %pc = 0x0805676D
      siginfo: SIGSEGV SEGV_MAPERR addr=0x0805676D
    Received signal #11, SIGSEGV [default]
      siginfo: SIGSEGV SEGV_MAPERR addr=0x0805676D


Is this a gdb bug ?
