yes the dynamic linker (ld*.so) has a different
assert implementation than libc.so:

https://sourceware.org/git/?p=glibc.git;a=blob;f=elf/dl-minimal.c;h=b37abfaff919383a1f1217f94798c65a0a70f398;hb=HEAD#l280

it calls _dl_fatal_printf which uses _exit(127)
and that will not dump core.

it might make sense to make ld.so asserts dump
core, please open a bug report about it.
