[linux-lvm] lvcreate segfalts 2.4.16 1.0.1-rc4

[Jesse Nelson]

Stock 2.4.16  and 1.0.1-rc4 LVM runing on RedHat 7.2 ( egcs 2.96

I read this post:
http://lists.sistina.com/pipermail/linux-lvm/2001-September/008980.html

About rc2 having same issue.
I compiled and patched with the patch mentioned in that post and it 
seems to be working.


heres the stack info for rc4:

[root@vader 1.0.1-rc2]# gdb lvcreate
	<snip>
(gdb) r -L 15G -n data vgData
Starting program: /sbin/lvcreate -L 15G -n data vgData

Program received signal SIGSEGV, Segmentation fault.

     rtld_fini=0x4000dc14 <_dl_fini>, stack_end=0xbffffa3c)
     at ../sysdeps/generic/libc-start.c:129
(gdb)



I will compile with debuging if it will help.


Thanks!

It's a Redhat compiler problem. You need to compile with -O0 or download 1.0.1
