[Bug c/23269] New: gcc doesn't remove half-written object file when compiling fails

[hg211 at ural2 dot hszk dot bme dot hu]

try to compile any erroneous C file (let's call it t.c) with

gcc -pipe -c -ot.o t.c

and gcc doesn't remove the half-generated t.o file.
Note that there's no space between -o and the output filename (and the -pipe is
necessary).
(the manual says that there should be a space between -o and the output
filename. However, everything works fine without it - except this)

straceing gcc reveals the cause of the problem: before exit, gcc stats '-ot.o',
not 't.o' - it thinks that the object file doesn't exist.

gcc version 4.0.2 20050725 (prerelease) (Debian 4.0.1-3)
but this problem exists in 3.3 and 3.4 too
