    I presume this is easy to fix. I presume it is the change position and not hiding a bug. The fix will probably be to just use decltype to ensure the type is the same as the one in the coin control struct?

    If the line in question is this one:

    0change_pos = txr.change_pos ? *txr.change_pos : -1;

    I’m not seeing the issue. change_pos is an int and txr.change_pos is an optional<unsigned int>.

    Yet, we could clean this code by making the CreatedTransactionResult struct reachable from the GUI code (just need to move it to another file).

    How can I reproduce the issue?

    I’ve tried on Ubuntu 22.04 with these configures:

    • ./configure --with-incompatible-bdb --enable-suppress-external-warnings --with-sqlite --without-bdb --with-sanitizers=undefined,integer CC=clang CXX=clang++
    • ./configure --with-incompatible-bdb --enable-suppress-external-warnings --with-sqlite --without-bdb --with-sanitizers=integer CC=clang CXX=clang++
    • ./configure --with-incompatible-bdb --enable-suppress-external-warnings --with-sqlite --without-bdb --with-sanitizers=signed-integer-overflow CC=clang CXX=clang++

    Got a lot of errors on the crypto library:

    Tried bitcoin-qt on regtest, sent some sats and got this (after the above):

    @pablomartin4btc Make sure to apply the existing suppressions, as explained in the docs.

    0$ git grep UBSAN doc/

    You can then also change halt_on_error=1 to halt_on_error=0, to continue execution when a new error was found.

  7. pablomartin4btc commented at 4:37 pm on March 27, 2024: contributor

    Thanks @maflcko, that worked and now I don’t get the unwanted errors.

    I’m sorry I still can’t reproduce the issue (on both master branches, this repo and bitcoin/bitcoin one):

    0export UBSAN_OPTIONS="suppressions=$(pwd)/test/sanitizer_suppressions/ubsan:print_stacktrace=1:halt_on_error=1:report_error_type=1"
1./configure --with-incompatible-bdb --enable-suppress-external-warnings --with-sqlite --without-bdb --with-sanitizers=undefined,integer CC=clang CXX=clang++

    Am I missing something else?

  8. maflcko commented at 6:15 pm on March 27, 2024: contributor

    IIRC, my steps were to start with a fresh regtest datadir, mine 101 blocks to a fresh wallet, then create a self-transfer transaction in the GUI.

    Did you do the same?

    I’m sorry I still can’t reproduce the issue (on both master branches, this repo and bitcoin/bitcoin one):

    The branches are identical (from the commit hash), as it expected in a monotree, so there is no need to check both.

  9. pablomartin4btc commented at 7:24 pm on March 27, 2024: contributor

    Did you do the same?

    I think I did but I have been using it for a while. Let me start fresh from scratch as you’ve well indicated it.

  10. pablomartin4btc commented at 9:05 pm on March 27, 2024: contributor

    I’ve managed to reproduce the issue now, thanks @maflcko!

    Tested on Ubuntu 22.04 following the steps described above ("… start with a fresh regtest datadir, mine 101 blocks to a fresh wallet, then create a self-transfer transaction in the GUI.").

32SUMMARY: UndefinedBehaviorSanitizer: implicit-integer-sign-change qt/walletview.cpp:137:21 in
  11. maflcko commented at 9:14 pm on March 27, 2024: contributor
    Nice, so you have reproduced all issues that I fixed in #806 ?
  12. pablomartin4btc commented at 9:23 pm on March 27, 2024: contributor
    I was already checking the PR and those issues actually, I got 2/ 3. Can’t reproduce the one starting with: wallet/interfaces.cpp:289:57: runtime error: implicit conversion from type 'int' of value -1, tried with both --with-sanitizers=undefined,integer and just --with-sanitizers=integer, any ideas?
  13. maflcko commented at 9:35 pm on March 27, 2024: contributor
    Did you make sure that no change (position) was specified in the GUI window? I don’t recall if I had “subtract fee from amount” enabled or not. Maybe try both?
