 |

gvba (GUI to VisualBoyAdvance) don't work and always gives me segmentation fault.
This is the strace output(last lines not all):
| Code: | stat64("/dev/sound", {st_mode=S_IFDIR|0755, st_size=160, ...}) = 0
stat64("/dev/sound/dsp", {st_mode=S_IFCHR|0660, st_rdev=makedev(14, 3), ...}) = 0
open("/dev/sound/dsp", O_WRONLY|O_NONBLOCK) = 7
fcntl64(7, F_GETFL) = 0x801 (flags O_WRONLY|O_NONBLOCK)
fcntl64(7, F_SETFL, O_WRONLY) = 0
ioctl(7, SNDCTL_DSP_GETFMTS, 0xbff736a8) = 0

Same here with stable 2.6.19-gentoo-r5 kernel. No solutions?
Edit: 'gvba' command segfaults, 'VisualBoyAdvance' not... maybe this is GTK related? |

Helpful GDB debugging tips (IMO, GDB kills strace in actual human readability).
- Don't compile with optimizations (Use -O0 and don't use -march or any of that crap)
- Compile with -g and -ggdb CFLAGS
- Compile with FEATURES="nostrip" in /etc/make.conf or heading your emerge line
It will give you usable results.. |

I filed a bug and submitted a patch with a fix, bug #171293
The problem was an uninitialized variable.
| Code: | if (m_poKeymap != NULL)
{
delete m_poKeymap;
}
|
m_poKeymap contained junk, because it wasn't initialized, and then this section of code would proceed to attempt to delete some random memory location according to whatever m_poKeymap happened to contain. |
