Bug ID: 70707
Summary: INT_MAX used before it is defined
Product: gcc
Version: 5.3.0
Status: UNCONFIRMED
Severity: trivial
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dethbomb at hotmail dot com
Target Milestone: ---
Im a complete newb to linux and gcc so please forgive if this is not the
correct way to do things. Or if this is not actually wrong then please ignore.
I saw what appeared to me to be incorrect C code while browsing "limits.h".
The following 2 cpp lines.
# define INT_MIN (-INT_MAX - 1)
# define INT_MAX 2147483647
INT_MAX is used before it is defined. The preprocessor seems to accept this in
gcc because INT_MAX is defined immediately afterwards.But if a different
preprocessor would be used this could cause problems?
printf("%i\n",INT_MIN);
does give the correct value. But im not sure if its because it may be defined
elsewhere in my source code thru some other header file.
regards,
Lewis
