-The OSSP lmtp2nntp program is an LMTP service for use in conjunction
-with an MTA (like Sendmail), providing a reli- able real-time mail to
-news gateway. Input messages get their headers slightly reformatted
-to match Usenet news article format. The article is then posted or
-feeded into a remote NNTP service (like INN). Delivery must take
-place immediately or the transaction fails. OSSP lmtp2nntp relies
-on the queuing capabilities of the MTA in order to provide a fully
-reliable service. For this the program returns proper delivery status
-notification which indi- cates successful completed action, persistent
-transient failure or permanent failure.

+
+    Bug 1876632 Fix aslr allocations on FreeBSD r=spidermonkey-reviewers,sfink
+    
+    Without the alignment flag the desired address
+    gets randomized by aslr in a way which causes it to not
+    be aligned. Furthermore the TryToAlignChunk almost always
+    fails. With this fix it never gets to TryToAlignChunk
+    because the flag guarantees upfront alignment.

+
+    Bug 1876632 Fix aslr allocations on FreeBSD r=spidermonkey-reviewers,sfink
+    
+    Without the alignment flag the desired address
+    gets randomized by aslr in a way which causes it to not
+    be aligned. Furthermore the TryToAlignChunk almost always
+    fails. With this fix it never gets to TryToAlignChunk
+    because the flag guarantees upfront alignment.
+
