http://gcc.gnu.org/bugzilla/show_bug.cgi?id=11810
Summary: gcc -pipe -ox.o -c x.c writes erroneous x.o on compile
error
Product: gcc
Version: 3.3.1
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: c
AssignedTo: unassigned at gcc dot gnu dot org
ReportedBy: deweese at ict dot usc dot edu
CC: gcc-bugs at gcc dot gnu dot org
GCC build triplet: i386-pc-linux-gnu
GCC host triplet: i386-pc-linux-gnu
GCC target triplet: i386-pc-linux-gnu
GCC incorrectly generates an output .o file even if there is a compiler
error under the following conditions:
-pipe is enabled, -c is enabled, and -o<objname>.o is specified.
The output object file is slightly different than an object file generated
from a C file without a minor compiler error, for example if the word ERROR
is added arbitrarily to the C file. Under these error conditions,
some symbols go missing from the output object file.
I have verified that the error occurs on gcc 2.95, 3.0.4, 3.2.3, and 3.3.1.
>How-To-Repeat:
Create a file "foo.c" with the following content, sans angle brackets:
>>>>
#include <stdio.h>
int main(int argc, char** argv) {
ERROR
printf("Hello World.\n");
return 0;
}
<<<<
Execute the following command with any version of gcc:
gcc -pipe -ofoo.o -c foo.c
The output is as follows:
foo.c: In function main':
foo.c:4: error: ERROR' undeclared (first use in this function)
foo.c:4: error: (Each undeclared identifier is reported only once
foo.c:4: error: for each function it appears in.)
foo.c:4: error: syntax error before "printf"
However, foo.o is written out. Subsequently, linking it causes an error:
gcc test.o
The output is:
/usr/lib/gcc-lib/i386-linux/3.3.1/../../../crt1.o(.text+0x18): In function
_start':
: undefined reference to main'
collect2: ld returned 1 exit status

I can confirm this on the mainline (20030805).
>From bug 10369 which is a dup:
I've tracked the problem: it is in gcc.c when executing the 'W' spec, it calls
add_temporary_file_name or such (don't remember the exact function name, don't have the
sources handy). The name that is passed to the function includes the -o switch (e.g.
add_temporary_file_name ("-ofile.o")) and on failure the driver tries to delete the file with this
name, and naturally fails.

Some more information the driver removes -ofoo.o instead of foo.o.

There are other problems with removing output files. For instance:
$ echo 'error!' > x
$ gcc -x c x -S
x:1: error: parse error before '!' token
$ ls
x x.s
$ rm x.s
$ gcc -x c x -save-temps -c
x:1: error: parse error before '!' token
$ ls
x x.i x.s

Similar problems also occur with PCH, see 9470.
