#368 init_console segfaults during exit(0) after fork

[Tobi Vollebregt]

I'm trying to use Allegro 4.4 on an embedded platform (ea3250 development board), using the Linux console and fbcon subsystems.

I found that a segmentation fault in ldlinux.so is triggered in the parent process after the fork in init_console (src/linux/lconsole.c) if install_keyboard is not called before set_gfx_mode. Unfortunately the trace is useless, and valgrind (from debian testing) doesn't work yet on ARM.

Allegro application is running on VT 2

Program received signal SIGSEGV, Segmentation fault.
0x40009cc4 in ?? () from /lib/ld-linux.so.3
(gdb) bt
#0  0x40009cc4 in ?? () from /lib/ld-linux.so.3

If install_keyboard is called before set_gfx_mode, no segmentation fault occurs. This leads me to believe the fbcon or linux console subsystem incorrectly assume install_keyboard has been called before.
