I created a small test I will attach to this bug report that shows that  
executables created with -fprofile-arcs -ftest-coverage crash in gcov_exit () 
if they dynamically load functions from libraries. 
 
I tested with gcc 3.4.1 and 4.0-20050213. Both show the same problem. 
 
Here's the gdb stack trace for both compilers: 
 
Program terminated with signal 11, Segmentation fault. 
 
#0  gcov_exit () at ../../gcc-3.4.1/gcc/libgcov.c:139 
139               if (!((1 << t_ix) & gi_ptr->ctr_mask)) 
(gdb) where 
#0  gcov_exit () at ../../gcc-3.4.1/gcc/libgcov.c:139 
#1  0x4018b820 in exit () from /lib/tls/libc.so.6 
#2  0x40176b1a in __libc_start_main () from /lib/tls/libc.so.6 
#3  0x080491b1 in _start () at ../sysdeps/i386/elf/start.S:119 
 
Program terminated with signal 11, Segmentation fault. 
 
#0  gcov_exit () at ../../gcc-4.0-20050213/gcc/libgcov.c:139 
139               if (!((1 << t_ix) & gi_ptr->ctr_mask)) 
((gdb) where 
#0  gcov_exit () at ../../gcc-4.0-20050213/gcc/libgcov.c:139 
#1  0x4018b820 in exit () from /lib/tls/libc.so.6 
#2  0x40176b1a in __libc_start_main () from /lib/tls/libc.so.6 
#3  0x08049031 in _start () at ../sysdeps/i386/elf/start.S:119 
 
 
The test uses SCons as a build tool. But I give the build arguments here for 
the 3.4.1 compiler: 
 
/opt2/GNU/bin/g++-3.4.1 -O0 -g -D_REENTRANT -W -Wall -Wpointer-arith 
-Wno-uninitialized -Woverloaded-virtual -Wcast-align -Wwrite-strings 
-Wcomments -march=pentiumpro -DCOVERAGE -fprofile-arcs -ftest-coverage -Isrc 
-c -o src/prog/.build/posix/coverage/main.o src/prog/main.cpp 
/opt2/GNU/bin/g++-3.4.1 -g -Wl,-E -o bin/posix/coverage/prog 
src/prog/.build/posix/coverage/main.o -Llib/posix/coverage -lstdc++ -lpthread 
-lrt -ldl -lgcov 
 
/opt2/GNU/bin/g++-3.4.1 -O0 -g -D_REENTRANT -W -Wall -Wpointer-arith 
-Wno-uninitialized -Woverloaded-virtual -Wcast-align -Wwrite-strings 
-Wcomments -march=pentiumpro -DCOVERAGE -fprofile-arcs -ftest-coverage -fPIC 
-Isrc -c -o src/calc/.build/posix/coverage/calc.os src/calc/calc.cpp 
 
/opt2/GNU/bin/g++-3.4.1 -g -Wl,-E -Wl,-soname=libcalc.so.1.0 -shared -o 
lib/posix/coverage/libcalc.so src/calc/.build/posix/coverage/calc.os 
-Llib/posix/coverage -lstdc++ -lpthread -lrt -ldl -lgcov
