Created attachment 1333449 [details] Patch file applied to source during rpmbuild Description of problem: SIGSEGV can occur in two locations in htdig/Parseable.cc where a NULL pointer is dereferenced. These locations were apparently recently tweaked in order to get the updated compiler to accept the code, but a slightly wider inspection window shows that the pointer had to be NULL in order to ever exit the subroutine. Version-Release number of selected component (if applicable): htdig-3.2.0-0.27.b6.fc26.x86_64.rpm How reproducible: - Rock solid Steps to Reproduce: 1. Install htdig 2. run rundig 3. Actual results: rundig fails complaining of segment violation. Expected results: htdig should start a "crawl and parse" based on the configuration Additional info: Attached is the patch file that I altered to fix the issue. This should replace the file of the same name.
