Subject: index-pack: report error using the correct variable
X-Git-Tag: v1.9.2~14^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=de983a0a1817437fbb0db938ecf91f73023a5f87;p=git

index-pack: report error using the correct variable

We feed a string pointer that is potentially NULL to die() when
showing the message.  Don't.
