Subject: Ensure duplinvolvedmap_all is reset when a solver is reused
X-Git-Tag: 0.7.23~54^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=dd6e977782816e330a8f60cf78ca3d12fead3b10;p=thirdparty%2Flibsolv.git

Ensure duplinvolvedmap_all is reset when a solver is reused

Otherwise, if solver is used with a SOLVER_DISTUPGRADE job, then reused
without one, this will cause solver_addduprules() to be called, even
though needduprules is 0, which will crash trying to dereference
solv->dupmap, which is NULL because solver_createdupmaps() hasn't been
called.
