And nada. Zilch. To be on the safe side I cat-ed through the map
file...no reference to dlopen anywhere. And, as mentioned earlier, no
mapfile is generated for the 4.9 libgcc build.
I'm going to go back a step and add the -Wl,-Map=mapfile flag to both
the 4.9 and 4.8 gcc Makefiles and run make clean && make, but if you
or anyone else watching this email thread have a better suggestion
please let me know.
