>Description:
When I try to run the palemoon browser under gdb on macppc, I get a strange
palemoon.core file:
[New process 2247]
Core was generated by `palemoon'.
Program terminated with signal SIGTRAP, Trace/breakpoint trap.

The source is:
135 void *gtk3 = dlopen("libgtk-3.so.0", RTLD_LOCAL | RTLD_LAZY);
It is not clear to me under what circumstances a SIGTRAP (as issued by
_rtld_debug_state(), trying to inform the debugger of the new shared lib
loaded) would cause a core dump while running under a debugger.
>How-To-Repeat:
just try to gdb something like firefox52 or palemoon?
What I actually did: cd to the pkgbuild work dir, there:
cd build/dist/bin
./run-mozilla.sh -g ./palemoon
and then at the gdb prompt:
run
