[Rpm-maint] rpm-4.9 segfault on build with empty prep section

[Michael Schroeder]

Hi,

rpm-4.9 will crash if the %prep section is empty, i.e. if
the specfile looks like:

%prep
%build
...

Patch (untested):

--- build/parsePrep.c.orig	2011-05-13 16:22:59.000000000 +0000
+++ build/parsePrep.c	2011-05-13 16:23:41.000000000 +0000

-    for (ARGV_const_t lines = saveLines; *lines; lines++) {
+    for (ARGV_const_t lines = saveLines; lines && *lines; lines++) {
 	res = 0;
 	if (rstreqn(*lines, "%setup", sizeof("%setup")-1)) {
 	    res = doSetupMacro(spec, *lines);


Cheers,
  Michael.
