/* I'm running gdb 3.4 under 386/ix 2.0.2, which is a derivative of AT&T's
|
| 25 |
|
|
Sys V/386 3.2.
|
| 26 |
|
|
|
| 27 |
|
|
On some machines, gdb crashes when it's starting up while calling the
|
| 28 |
|
|
vendor's termio tgetent() routine. It always works when run under
|
| 29 |
|
|
itself (actually, under 3.2, it's not an infinitely recursive bug.)
|
| 30 |
|
|
After some poking around, it appears that depending on the environment
|
| 31 |
|
|
size, or whether you're running YP, or the phase of the moon or something,
|
| 32 |
|
|
the stack is not always long-aligned when main() is called, and tgetent()
|
| 33 |
|
|
takes strong offense at that. On some machines this bug never appears, but
|
| 34 |
|
|
on those where it does, it occurs quite reliably. */
