Try fprintf(stderr, "%p\n", v); to see if the pointer value has become corrupted somehow.

If all you're passing is one integer, why allocate memory at all?

void *value=(void *)42;
int ivalue=(int)(value);

If that's not all you're doing, post a more complete portion of your code so we can see what's actually going on.

PAPI_strerror(3)						       PAPI							  PAPI_strerror(3)

NAME
PAPI_strerror - Returns a string describing the PAPI error code. SYNOPSIS
Detailed Description C Interface: #include <papi.h> char * PAPI_strerror( int errorCode ); Parameters: code -- the error code to interpret Return values: *error -- a pointer to the error string. NULL -- the input error code to PAPI_strerror() is invalid. PAPI_strerror() returns a pointer to the error message corresponding to the error code code. If the call fails the function returns the NULL pointer. This function is not implemented in Fortran. Example: * int ret; * int EventSet = PAPI_NULL; * int native = 0x0; * char error_str[PAPI_MAX_STR_LEN]; * * ret = PAPI_create_eventset(&EventSet); * if (ret != PAPI_OK) * { * fprintf(stderr, "PAPI error %d: %s0, ret, PAPI_strerror(retval)); * exit(1); * } * // Add Total Instructions Executed to our EventSet * ret = PAPI_add_event(EventSet, PAPI_TOT_INS); * if (ret != PAPI_OK) * { * PAPI_perror( "PAPI_add_event"); * fprintf(stderr,"PAPI_error %d: %s0, ret, error_str); * exit(1); * } * // Start counting * ret = PAPI_start(EventSet); * if (ret != PAPI_OK) handle_error(ret); * See Also: PAPI_perror PAPI_set_opt PAPI_get_opt PAPI_shutdown PAPI_set_debug Author Generated automatically by Doxygen for PAPI from the source code.
