Bug #: 56403 Summary: internal compiler error: in build_zero_init_1, at cp/init.c:279 Classification: Unclassified Product: gcc Version: 4.7.2 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassig...@gcc.gnu.org ReportedBy: aseer...@vertica.com Created attachment 29504 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=29504 Preprocessed output from the source files that reproduce this bug (I'm re-filing this bug per suggestion from the downstream Ubuntu bug tracker: <https://bugs.launchpad.net/ubuntu/+source/gcc-4.6/+bug/1093055> Upon further investigation, the bug doesn't appear to be Ubuntu-specific.) I've hit this bug on several g++ versions, but am primarily running 4.6.3 as bundled with Ubuntu 12.04, on a relatively stock system: $ gcc -v Using built-in specs.

When I compile it as follows, I get the following error: $ g++ -I ../include -I HelperLibraries -g -Wall -Wno-unused-value -shared -fPIC -o build/BasicIntegerParser_continuous.so ParserFunctions/BasicIntegerParser_continuous.cpp ../include/Vertica.cpp ParserFunctions/BasicIntegerParser_continuous.cpp: In member function ‘virtual Vertica::UDParser* BasicIntegerParserFactory::prepare(Vertica::ServerInterface&, Vertica::PerColumnParamReader&, Vertica::PlanContext&, const Vertica::SizedColumnTypes&)’: ParserFunctions/BasicIntegerParser_continuous.cpp:76:16: internal compiler error: in build_zero_init_1, at cp/init.c:279 Please submit a full bug report, with preprocessed source if appropriate. See <file:///usr/share/doc/gcc-4.6/README.Bugs> for instructions. Preprocessed source stored into /tmp/cc8HZt1y.out file, please attach this to your bugreport. I expected the file to compile properly, or at least provide an error message describing a fault in my code rather than in the compiler. I have attached the preprocessed source file as requested by the error message. The error reproduces for me on g++ 4.4.5 (installed on top of Red Hat Enterprise Linux -- hence concluding no Ubuntu dependency). Others have reproduced this with both vanilla and Ubuntu-packaged g++ 4.7.2. The bug does NOT reproduce for me on g++ 4.1.2; the above code compiles and runs as I would expect: $ gcc -v Using built-in specs.

(I suspect that's not too useful for debugging, but, just in case / to be thorough.) Please let me know if I can help out in debugging or fixing.
