So the problem goes away if you run it under gdb. So much for
If you have strace, ltrace or equivalent, you could try using those.

If gdb understands your existing binary, -g is equivalent to -ggdb.
Some versions of gcc/binutils understand multiple debug formats, in
which case you can use -ggdb, -gdwarf, -gstabs etc to select a
specific format. If you just use -g, it will use the default debug
format, which is usually gdb.
