Bug #: 51745
Summary: Strange symbol appears when using commandline
definition without "="
Classification: Unclassified
Product: gcc
Version: 4.6.2
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: preprocessor
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: miku...@artax.karlin.mff.cuni.cz
Host: i686-pc-linux-gnu
Target: i686-pc-linux-gnu
Build: i686-pc-linux-gnu
If we use -D definition without "=" in the command line, strange unwanted
symbol "1" appears in the output.
How to reproduce: run gcc -E - -o - "-Dblabla(x, y) bleble[x,y]"
Type blabla(2,3) and press Ctrl-D.
The output is: bleble[2,3] 1
The symbol "1" was never defined anywhere. There is something strange going on
in the commandline parsing. Such syntax without "=" should be either rejected
with an error or it should be processed correctly.
