#13370: Boost Spirit Stack Smash with BOOST_SPIRIT_DEBUG defined
Reporter: chrisfriedt@â¦ | Owner: Joel de Guzman
Type: Bugs | Status: new
Milestone: To Be Determined | Component: spirit
Version: Boost 1.65.0 | Severity: Problem
I think I've found some code that touches on a boost::spirit soft-spot
that causes a stack overflow when BOOST_SPIRIT_DEBUG is defined, but when
debug is not defined, just does not work, *specifically* on Linux.
I don't pretend to know why it happens, but it works perfectly well on Mac
OS X. The only thing I know is that a stack smash is reported by GCC after
boost::spirit::qi::parse() is called.
I have this body of code that uses boost::spirit and thrift. I'm using TDD
with gtest and developing primarily on Mac OS X. Recently, I added CI
using GitLab and the Docker runner, so the testsuites are being run in a
pseudo-GNU / Linux environment, but then I also tried it in a Linux VM
with the same results, so it's definitely somehow related to Linux. I even
tried compiling with clang under Linux, with the same results.
Sorry for submitting my whole project source, but this is the only way
I've been able to trigger it reliably. To build the code
and then run:
It should be reproducible (i.e. the stack will be smashed) on Linux, but
not on Mac OS X.
Also, if you remove --enable-debug, clean, and rebuild, then the stack
will not be smashed, but the parser will fail under Linux, but not Mac OS
The listing named below is an example program that triggers the smashed
stack. I've reproduced this with GCC versions as old as 4.6 and as recent
as 7.2 and have tried it with boost versions 1.58 and 1.65.1 . The thrift
version I'm using is 0.11.0.
The following two named test suites fail under Linux but pass under Mac OS
My code is still pre-alpha, so I haven't released it at all yet... but you
might guess it's an Apache Thrift interface to GDB's RSP.
I might not have written the best boost::spirit parsers, but regardless,
the behaviour should be similar across different compilers and OS's.
Please let me know if I can help isolate the problem. I have tried a ton
of things, including valgrind, and just have no idea.
Also, I'm sure that my code is horrible. Please don't judge me, but feel
free to offer better suggestions (using boost::spirit) that do not trigger
stack smashes :-)
If anyone is able to *not* reproduce the stack smash using Linux, I would
also be very curious to hear back about it.
