#13370: Boost Spirit Stack Smash with BOOST_SPIRIT_DEBUG defined
 Reporter: chrisfriedt@… | Owner: Joel de Guzman
     Type: Bugs | Status: new
Milestone: To Be Determined | Component: spirit
  Version: Boost 1.65.0 | Severity: Problem
 Keywords: |

 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:

 sh autogen.sh
 ./configure --enable-debug

 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.
