Description Fred_busybox 2011-08-09 15:39:45 UTC

Hi,

I have a issue, I don't know if it s gdb or not. and how to solve ( I have tried 3 kind of gdb version , there was working with my previous toolchain)

When I boot my binary with gdb 

Program received signal SIGSEGV, Segmentation fault.
0x00000000 in ?? ()
(gdb) bt
#0  0x00000000 in ?? ()
#1  0x00441038 in main (argc=4, argv=0x7ff97de4) at file.c:135
(gdb) q
A debugging session is active.

on a called to setvbuf


Strangly, if I force the LD_BIND_NOW=1 before launching gdb,  I have no error.


Do you see something strange on my config in attachment ?


Should I update the ucluibc0.9.32 for the dailybuild ?  is there some news feature for mipsel support ?


Miss I something in my rootfs?  I am lost...

Thanks
