When I call EM::stop from within a Deferrable callback, I''m getting the following: terminate called after throwing an instance of ''std::runtime_error'' what(): already initialized Abort trap Is there any way to trace this a little further? -- Duane Johnson

...example, I modified the code in https://github.com/llvm-mirror/llvm/tree/master/examples/Kaleidoscope/BuildingAJIT/Chapter2. In toy.cpp, I update LogError to throw an exception: std::unique_ptr<ExprAST> LogError(const char *Str) { fprintf(stderr, "Error: %s\n", Str); throw std::runtime_error(""); } and I catch that exception in MainLoop: static void MainLoop() { while (true) { fprintf(stderr, "ready> "); try { switch (CurTok) { ... } } catch (std::runtime_error &e) { fprintf(stderr, "%s\n", e.what()); }...

Hi Duncan, There's a problem with your check-in for r72619 is causing "weak external" symbols to appear in C++ code when it shouldn't. Take this code for example, #include <stdexcept> void dummysymbol() { throw(std::runtime_error("string")); } The c'tor for std::string is emitted as code from llvm-gcc. It is then inlined. And a weak external for the `_S_construct' variable is created. However, C++ rules stipulate that it shouldn't be, because of explicit & implicit template instantiation rul...

I know this error has been reported before, but a couple ppl have reported getting this randomly when running Thin and it crashed the server: terminate called after throwing an instance of ''std::runtime_error'' what(): unable to delete epoll event: Bad file descriptor I think it''s fixed on trunk now so I''m telling people that have this issue to checkout and install EM from trunk.

Hi I'm trying to implement something similar to the following R snippet using C. I seem to have hit the wall on accessing class slots using C. library(fPortfolio) lppData <- 100 * LPP2005.RET[, 1:6] ewSpec <- portfolioSpec() nAssets <- ncol(lppData) setWeights(ewSpec) <- rep(1/nAssets, times = nAssets) ewPortfolio <- feasiblePortfolio( data = lppData, spec = ewSpec,

...through LLVM JITed code? To illustrate the problem a bit better, consider this psuedo code. I want the exception thrown in intrinsic_function(), which is called from the LLVM compiled code, to be caught by the exception handler at the bottom of run_program(). void intrinsic_function() { throw runtime_error("unimplemented function"); } void run_program() { char *script_code = "call intrinsic_function();"; try { myFunction = compile(script_code); Engine->runFunction(myFunction); } catch (...) { // This is never reached. } } I suspect this is not going to b...

In looking at the code I realized that the last of the HAL depenencies were removed with this patch. So, I'm pushing an updated patch that contains none of the HAL code in it.
