--- Comment #3 from v1ne2go at gmail.com ---
As a quick workaround, setting LD_BIND_NOW helps.
I tried this on gmp, which passes make check with this flag -- except C++ tests
due to broken exceptions.
Without this, I also got some
  ld-elf.so.1: assert failed: /usr/src/libexec/rtld-elf/rtld_lock.c:233
messages.

So, what exactly is the difference when lazy binding comes into play?
>From my underständing, if a symbol is not bound, the process is as follows:
- I call some function func(), stack is 8-byte aligned
- func points to an rtld handler that loads the function and patches the
function table, stack is 8-byte aligned at the start and we crash somewhere in
rtld.
- rtld calls func()

vs.
- I call func(), stack is 8-byte aligned at this point
- func is being called

Was there any progress since the last year?
