--- Begin Message ---Package: mawk Version: 1.3.3-16 Severity: serious Tags: upstream patch Hi, RC because this causes at least one other package to FTBFS with the current libc in sid. See #628247 for more details of that. We'd originally thought that was due to the output files being mashed during parallel builds, but the most recent rebuilds that Lucas did also proved that the exact same results could be reproduced with current libc on a single core system with a -j1 build. After further investigation, it turns out the recent changes to memcpy in libc have triggered a latent bug in mawk, making it mash the memory copied between overlapping regions. The existence of the bug in mawk was confirmed by valgrind, and the following patch is confirmed to fix the error that resulted from it. The code paths in mawk exercised by sofia-sip don't shake out any other instances of this, but I haven't exhaustively scanned the mawk code for any others at this stage.
