I was trying to use valgrind on one of my applications. The program runs fine
on its own, but valgrind reports a SIGSEGV and exits without running any of my
application, as far as I can tell.
I have been able to reproduce the issue with a simple test. The test does not
even use log4cxx, but just linking it in causes the problem, so likely some
static vars causing constructors, etc. to run maybe? Again, running the test
without valgrind does not cause a seg fault.
I am on Fedora Core 14, kernel 2.6.35.12-88, g++ 4.5.1, glibc-2.13.1.
Any help most appreciated,
Thanks,
Shash
Here's the content of my Test.cpp file:
int main(const int argc,
const char** argv)
{
return (0);
}
Here are the commands to build:
g++ -g -Wall -o Test.o -c src/Test.cpp
g++ -g Test.o -o test -llog4cxx
Running "valgrind ./test" gets:
