Got a link to this project with 120K strings in flash? I'd like to see the loader script and the .elf Thanks!

Well, I'm sorry to tell you, but your strings are not ending up in flash, except for the os_printf format strings, which go through a special macro. Take a look at the output of
xtensa-lx106-elf-objdump -j .rodata -s espiobridge-rboot.o
and you will see most of your strings. The rodata segment ends up in RAM, it's part of the ~39KB:
dram: available: 80 k, used: 39992, free: 41928, 51 %
You can see which strings end up in flash thanks to the os_printf macro by running
xtensa-lx106-elf-objdump -j .irom0.text -s espiobridge-rboot.o | less
and looking from the end of that output.

I stand corrected then!
Well I have still about 36 kbytes free, it appears, when running, so I guess it isn't such a big deal.
Are you really sure, also about strings declared: const char *bla = "bla"; ? And also with -f-no-writable-strings?
