indent: gnuindent -kr crashes

[jhi]

I'm trying to reformat the Perl C source files. The macports gnuindent 2.2.10 seems to crash (as in: segfault) on some files, when I use the -kr option for K&R style. The crash is fully reproducible. I cannot see a correlation between the size of the input file and a crash. I'm attaching one of the crash-inducing files, utf8.c, here for repro. Note: if run as

gnuindent -kr utf8.c

not only there is a segfault, but the utf8.c gets truncated, too (since by default gnu indent outputs to the input file...)

I'm running the latest macports, on OS X 10.9.2.

I tried indent in a Ubuntu precise, indent --version says there 2.2.11, no crashes.

The utf8.c you attached is already truncated; I get:

$ gnuindent -kr utf8.c
indent: utf8.c:1828: Error:Unexpected end of file

The latest version of indent on the ​GNU FTP site is 2.2.10. You should probably file this bug report with the developers of indent, and when they fix it and release a new version, then we can update the port in MacPorts to that version.

retrying attaching the sample file, hopefully untruncated

(1) I could try doing that, but looks like the GNU indent hasn't had a release for five years now. I hoped the turnaround time with macports would be shorter.

(2) I think what release number the Ubuntu GNU indent is showing is a red herring: what is relevant that with the same input the GNU indent doesn't crash in there, while it does crash in macports.

I still see this crash with 2.2.11.
