Source: sbcl Version: 2:1.5.6-1 Severity: normal Tags: patch User: [email protected] Usertags: alpha Hi! While bootstrapping sbcl on alpha, I ran into an issue that was introduced in 3bdf881c145682c86b511af4117b0c617b28353d (Change heap-reloc test not to override mmap() via LD_PRELOAD). The attached patch fixes this issue, could you include it in the next upload? I have already posted it upstream on sbcl-devel/sbcl-bugs. Thanks, Adrian -- .''`.
