bug #27148: Use of strcpy on overlapping memory areas
|
||||
http://savannah.gnu.org/bugs/?27148
|
||||
http://cvs.savannah.gnu.org/viewvc/make/job.c?root=make&r1=1.194&r2=1.195

|
||||
* job.c (new_job): Use memmove() instead of strcpy() since both
|
||||
pointers are in the same memory block. Fixes Savannah bug #27148.
|
||||
Patch by Petr Machata.
|
||||
|
||||
bug #22010: The increased stack rlimit is inherited by the subprocesses to make.

|
||||
* make.h: Move SET_STACK_SIZE determination to make.h.
|
||||
* main.c (main): New global variable, STACK_LIMIT, holds the
|
||||
original stack limit when make was started.
|
||||
* job.c (start_job_command): Reset the stack limit, if we changed it.
|
||||
Fixes Savannah bug #22010.
