Bug#949952: tilix does not start on arm64 (maybe libunwind related)

Sat Feb 1 01:27:05 GMT 2020

Hello Birger Schacht,
I tried to get some more information from this issue.

To be sure where your tilix aborts you would need to
install gdb and at least tilix-dbgsym [1] and
run it this way:

    gdb -q -ex 'set pagination off' -ex run -ex bt -ex detach -ex quit --args tilix

Then I guess you see an backtrace like this:

    (gdb) bt
    #0  __GI_raise (sig=sig at entry=6) at ../sysdeps/unix/sysv/linux/raise.c:50
    #1  0x0000fffff690aea8 in __GI_abort () at abort.c:79
    #2  0x0000fffff6b3f544 in _d_throw_exception () from /lib/aarch64-linux-gnu/libdruntime-ldc-shared.so.88
    #3  0x0000aaaaaac73528 in _D3std9exception__T7bailOutHTC9ExceptionZQwFNaNfAyamMAxaZv (line=<optimized out>, msg=..., file=...) at /usr/lib/ldc/aarch64-linux-gnu/include/d/std/exception.d:516
    #4  _D3std9exception__T7enforceZ__TQmTbZQrFNaNfbLAxaAyamZb (value=<optimized out>, msg=..., file=..., line=<optimized out>) at /usr/lib/ldc/aarch64-linux-gnu/include/d/std/exception.d:436
    #5  0x0000fffff6e44610 in std.process.environment.opIndex(scope const(char)[]) () from /lib/aarch64-linux-gnu/libphobos2-ldc-shared.so.88
    #6  0x0000aaaaaac2874c in D main (args=...) at app.d:127

After looking at the source [2] I assume this might not be
fatal and the program not be aborted.

You might be able to confirm if this workaround works
for you too, by starting with this LD_PRELOAD:

    LD_PRELOAD=/lib/aarch64-linux-gnu/libgcc_s.so.1 tilix

This might be related to exceptions in libunwind.so.8.
There exists a similar ticket which is also related to
exception handling with the same workaround [3].

Unfortunately there was not yet much response from
libunwind downstream or upstream.

Kind regards,
Bernhard

Maybe related, because same workaround and related to exceptions:

Kind of related: Upstream tests do not link to libunwind.so, therefore testing libgcc_s.so exception handler:
