We did, and the solution was in boost-log for our code base. You probably have some static data somewhere that is not being properly initialized. Hopefully this will help someone else encountering this bug. Is anyone out there able to give more insight into this problem? Is there an actual solution or do only workarounds exist?įollowing Michael Dorgan's suggestion, I'm copying my comment into an answer:įound the real cause of the problem. Because using SWIG (or boost::python) is a common way of calling a C++ library from a C application, that is why SWIG often comes up when researching the problem. The problem occurs only with C applications calling C++ libraries because the C application is not itself linking to libstdc++ and is not initializing the C++ runtime. By forcing the order of linking you bootstrap the initialization process and it works. My understanding of the issue is that the C++ runtime is not being properly initialized. That is, none of the compile-time linking solutions made any difference. The "solution" is to explicitly link your library with libstdc++ and possibly also with libGL, forcing the order of linking.Īfter trying many combinations with my code, the only solution that I found that works is the LD_PRELOAD="libGL.so libstdc++.so.6" ruby scriptname option. The problem does not occur when linking your library with a C++ application, only with a C application.Generally the second version of C++ used comes from a binary-only implementation of libGL.More than one version of libstdc++ was used during compilation.A C application is linked to more than one C++ library.The overriding theme seems to be a combination of circumstances: I've found several references to similar problems, including: Neither GDB nor valgrind provided any insight into the cause of the crash. I'm not sure of the specific circumstances to recreate the issue, but it happened first during a call to std::uncaught_exception, then after a some code changes, moved to _cxa_allocate_exception during exception construction. digit-0.8: A data-type representing digits 0-9 and otherĭ0,, ,, ,, Data.While developing a SWIG wrapped C++ library for Ruby, we came across an unexplained crash during exception handling inside the C++ code. it also forces all other letters to lowercase, otherwise mixedCase words will retain capital letters in the middle of words. ucfirst: Uppercase the first letter in each word in jmw86069 S-equals? s-matches? s-blank? s-ends-with? s-starts-with? s-contains? s-lowercase? s-uppercase? s-mixedcase? s-capitalized? s-titleized? s-numeric?
