The backtrace is strange.  Did you compiled malloc with the debugging
symbols, while keep rest of libc without -g ?
I've just added the -g flag to CC_FLAGS in the Makefile and made sure to
install an unstripped version of the .so . I could investigate more on
why the early calls omit debug symbols, if it does any matter.
I want to understand at what stage of the initialization the access happens.
This is why I want to see the complete backtrace.

It is jemalloc_constructor() that calls malloc_init(), so it should be called directly by the loader.
