Same with epel9
Same with epel9 and dcmtk 3.6.6 3.6.7 seems to build successfully and no more segmentation fault
For me 3.6.8 is also ok, no segfaults.
Based on this Ubuntu bug report [0], the fix for CVE-2021-41687 introduced a regression. That has been fixed upstream [1]. I've submitted that commit as a backport patch for the EPEL 8 [2] and EPEL 9 [3] packages. If anyone is able, please test out the scratch build RPMs [4][5] to see if this is sufficient to resolve the issue.
