Bug ID: 89249
Summary: mingw, paths with space, LTO -> collect2.exe: fatal
error: CreateProcess: No such file or directory
Product: gcc
Version: 8.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: ilg at livius dot net
Target Milestone: ---
I know that supporting Windows was always a big pain, so I can fully understand
people not being over joyed when seeing such errors...
I also noticed that reports related to CreateProcess are usually refered to
mingw; or that local configurations are blamed, like wrong paths.
However, in my case, the specifics may point to a possible bug in gcc, althougt
I do not exclude an interraction with the mingw runtime.
The problem occured in a configuration which used spaces in the install path,
and went away when I moved **exactly** the same toolchain to a folder without
spaces in the names.
Another detail is that the problem occured only when using -flto, and did not
occur when exactly the same project was compiled without -flto.
The linker output with the error:

I might be wrong, but, if I read the message 'collect2.exe: fatal error:
CreateProcess...' correctly, it looks like collect2 is not able to start a
subprocess, probably lto-wrapper.exe or lto1.exe.
A possible reason for this is that collect2 gets confused by the space in the
path. lto*.exe are not in the system path, only '<top>/bin' is, where gcc/g++
are located. From here gcc/g++ probably compute a relative path to
'<top>/libexec/gcc/arm-none-eabi/8.2.1', where they find collect2.
collect2 must do the same to locate lto*.exe.
I'm not very familiar with the source code, so I don't know exactly where to
search for, but one starting point would be to investigate why gcc/g++ properly
identify collect2, and collect2 fails to identify lto*. Normally they shuld all
share the code to compute the relative path, but maybe they do not, or do not
call it the same.
If someone with more deep knowledge on how things work can suggest a place to
add extra debug messages, I can build new binaries to further investigate.
