Hmmm... This is very odd. Not just the error, but also the NULL error message.
The proble is caused by a failing 'opendir(".")' system call, which causes
logerr_die( ... ) to be called, which calls Errormsg() to be called, which will
cause the strerror() routine to be called. Apparently the AIX strerror() return
does not include error messages for the failure.
I will modify the 'Errormsg()' code to cover this case:
Errormsg( int err ){
if( !(msg = strerror(err)) ){
static char b[32];
snprintf(b,sizeof(b),"errno=%d", err );
msg = b;
}
return(msg);
