Bug ID: 366131
Summary: Illegal opcode in OS X 11.0 when using function
getpwuid()
Product: valgrind
Version: 3.11.0
Platform: MacPorts Packages
OS: OS X
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: memcheck
Assignee: [email protected]
Reporter: [email protected]
The following code snippet:
#include <unistd.h>
#include <sys/types.h>
#include <pwd.h>
int main()
{
struct passwd *pw = getpwuid(getuid());
}
generates the following error message:
==88748== valgrind: Unrecognised instruction at address 0x10043bb34.
...
and raises SIGILL signal. The full stacktrace is as follows:
==88782== at 0x10043BB34: OSAtomicEnqueue (in
/usr/lib/system/libsystem_platform.dylib)
==88782== by 0x1004ABFD7: _xpc_dictionary_apply_node_f_wire_apply (in

==88782== by 0x100000F7F: main (in ./test_getpwuid)
Valgrind has been installed from macports, and the code snippet has been
compiled simply as
gcc -o test_getpwuid test_getpwuid.c
