First, as a workaround, maybe you can try:

$ TEST_NO_MALLOC_CHECK=1 ./t0000-basic.sh -i -v

to see if things work when disabling malloc checks.

Anyway the issue might be related to how your shared libraries are installed, so using ldconfig might help:

$ sudo ldconfig

Alternatively you can try replacing the following line in t/test-lib.sh:

                 LD_PRELOAD="libc_malloc_debug.so.0"

with:

                 LD_PRELOAD="/usr/lib/libc_malloc_debug.so.0"

This is a hack but it might help understand what's going on if it works.

Yeah, not sure why it doesn't work while you have it.

Best, Christian.
