| /* I'm running gdb 3.4 under 386/ix 2.0.2, which is a derivative of AT&T's |
| Sys V/386 3.2. |
| |
| On some machines, gdb crashes when it's starting up while calling the |
| vendor's termio tgetent() routine. It always works when run under |
| itself (actually, under 3.2, it's not an infinitely recursive bug.) |
| After some poking around, it appears that depending on the environment |
| size, or whether you're running YP, or the phase of the moon or something, |
| the stack is not always long-aligned when main() is called, and tgetent() |
| takes strong offense at that. On some machines this bug never appears, but |
| on those where it does, it occurs quite reliably. */ |
