Re: [linux-lvm] lvcreate seg faults in 1.0.1-r4

[Francis SOUYRI <francis.souyri@wanadoo.fr>]

  Hello Tim,

    You have a problem with gcc 2.96 (I have the same problem with a 
RedHat 7.2 gcc 2.96), Change in the file "<lvm_path_source>/make.tmpl" 
the line "CFLAGS+= -g -O2 -Wall -pg" by "CFLAGS+= -g -O0 -Wall -pg" and 
recompile the lvm utilities.

Best regards

Francis
