SIGSEGV running FDM

[tsingkong]

Steps to reproduce:
clone sources from git
$ mkdir build; cd build; cmake .. -D LARCH64=1 -D BO64=1 -D BO64_BINFMT=1 -D CMAKE_BUILD_TYPE=RelWithDebInfo
$ make -j4
extract FDM(https://files2.freedownloadmanager.org/6/latest/freedownloadmanager.deb) to /opt
$ export BOX64_LD_LIBRARY_PATH=/data/ACE/bookworm-env/usr/lib/x86_64-linux-gnu:/opt/freedownloadmanager/lib
$ BOX64_TRACE_FILE=/tmp/box64-002.log BOX64_LOG=debug /opt/freedownloadmanager/fdm

box64-002.log

[ksco]

I'll look into this soon.

Note on the issue submission: 1) please do not use BOX64_LOG=debug unless asked to, it's almost always too verbose for debugging; 2) there are no such parameters in box64: -D BO64=1 -D BO64_BINFMT=1, so these does not have any effects, please read the compilation documentation here: https://github.com/ptitSeb/box64/blob/main/docs/COMPILE.md.

I've added the missing wrappers in #2105, but there are still other issues.

[tsingkong]

I've added the missing wrappers in #2105, but there are still other issues.

Thanks for your effort.
I checkout the patch(#2105) and rebuild box64, the new log as following:

I added another fix above, it goes further, but still not enough :(

But now, the error is exactly the same on aarch64 too, so this becomes a box64 issue in general, I updated the title.

Put libdbus-1.so.3 under lib, then not reproduced the dbus issue for KP920 or 3A5000, but slipped into infinite loop:
