To: gdb-prs
gdb version: 7.1, OS: Red Hat Enterprise Linux Client release 5.3 (Tikanga)
Reproduce steps:
1. build a shared library:
source code (file shared.c):
int add(int a, int b)
{
return a+b;
}
gcc -m32 -fpic -shared shared.c -o libmyshared.so
2. build an executable
source code (main.c)
#include <stdio.h>
#include <dlfcn.h>
void openlibrary()
{
void *handle = dlopen("./libmyshared.so", RTLD_LAZY);
if(handle!=NULL)
{
printf("open successully\n");
dclose(handle);
}
else
{
fprintf(stderr, "%s\n", dlerror());
}
}
int main()
{
return 0;
}
gcc -m32 -g main.c -ldl
3. launch the debugger by command "gdb a.out"
then in the command line interface:
1) input "b main", then type enter
2) input "run", then type enter
3) input "c openlibrary()", then type enter
4) repeat step 3 at most 50 times, then the gdb terminates. This behavior is
unexpected.
Note: this bug doesn't exist in 6.8-27.el5

------- Additional Comments From pedro at codesourcery dot com 2010-06-03 11:23 -------
I think this was fixed shortly after 7.1 was released. Please try a recent
snapshot or cvs mainline.
