[uClibc]0.9.19: Memory fault with setjmp on arm7tdmi

[Markus Pietrek]

Hi folks,

just compiled uClibc-0.9.19 for an NetARM+50 (arm7tdmi)/uclinux-2.4.20 and 
I'am impressed. All went smooth and the gcc wrapper makes life much easier 
now :-)

The applications I tested so far work fine. But using setjmp() results in an 
"Memory fault", even the uclibc-0.9.19 setjmp_test

=== On the host ===

Compiling vs uClibc:

../../extra/gcc-uClibc/arm-uclibc-gcc --uclibc-use-build-dir  -Wall 
-Wstrict-prototypes -O0   -g -c setjmp_test.c -o setjmp_test.o
../../extra/gcc-uClibc/arm-uclibc-gcc -elf2flt --uclibc-use-build-dir -g 
-Wl,-warn-common setjmp_test.o -o setjmp_test
true -Since_we_are_debugging -x -R .note -R .comment setjmp_test

=== On the target ===

# /nfs/setjmp_test
Memory fault

===

Is there some compiler option missing?  I attached my .config file for uClibc.

Best regards,
