After this commit, __dlopen is now: ``` void * __dlopen (const char *file, int mode, void *dl_caller) { return dlopen_implementation (file, mode, RETURN_ADDRESS (0)); } ``` This seems like it may be a bug, because the `dl_caller` argument to `__dlopen` is now ignored. I don't have a concrete case where this causes any problems, this was just noticed by inspection, but it looked wrong. -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 4+ messages in thread
