Yes, I tried that approach, and it did not improve the situation.

No. :-(  Perhaps it is the toolchain versions?  I did this build on
Fedora Rawhide, which is currently using gcc 4.9.1 and binutils 2.24.

They have something to do with the stack unwinding and backtrace
printing code.  I'm afraid that I don't know a lot about the ARM
platform.

Maybe.  I used to block -fstack-protector from being used, because it
caused the build to fail.  However, I read that you had done some work
to make that flag safe to use, so I stopped blocking it.  It is
possible that that has something to do with this problem.  The
Fedora-specific CFLAGS in use are:

-g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2
-fexceptions -fstack-protector-strong --param=ssp-buffer-size=4
-grecord-gcc-switches -fno-omit-frame-pointer -march=armv7-a
-mfpu=vfpv3-d16 -mfloat-abi=hard

Maybe -fexceptions is responsible?
