Dear maintainer:

During a rebuild of all packages in unstable, this package failed to build.

Below you will find the last part of the build log (probably the most
relevant part, but not necessarily). If required, the full build log
is available here:

https://people.debian.org/~sanvila/build-logs/202606/

About the archive rebuild: The build was made on virtual machines from AWS,
using sbuild and a reduced chroot with only build-essential packages.

Note: The bug happens randomly, but more than 50% of the time here.
If you cannot reproduce the bug please contact me privately, as I am
willing to provide ssh access to a virtual machine where this
randomness happens.

If this is really a bug in one of the build-depends, please use
reassign and add an affects on src:terraphast, so that this is still
visible in the BTS web page for this package.

Thanks.

Hello,

Bug #1139550 in terraphast reported by you has been fixed in the
Git repository and is awaiting an upload. You can see the commit
message below and you can check the diff of the fix at:

https://salsa.debian.org/med-team/terraphast/-/commit/ed32ca4ddd5f632b1ca2346e06a608920e01fa57
When the multitree memory limit is hit, begin_iteration() returns an
unexplored node because the alternative array could not be allocated, but
continue_iteration() still returned true (the memory accounting was below
the limit).  The iteration loop then called accumulate() on the unexplored
node, writing a full multitree_node (including a GMP big_integer) into the
leaf array of the unexplored node.  This corrupted the heap and could
abort with a 'realloc(): invalid pointer' inside GMP, making the unittests
fail randomly (FTBFS).

Mark the memory limit as hit whenever begin_iteration() has to fall back
to an unexplored node so that continue_iteration() stops the iteration.
