Re: gdb crashes with Solaris 10 x86

[Richard Walter <Richard.Walter@hob.de>]

There are two platforms where the problem occurs, a sunfire with 2 AMD
processors and a virtual machine on vmware.
The OS is Solaris 10 X86 03/05

When the segmentation fault happens the gdb ends and i get a shell
prompt.
