g++ 3.2 crashes on the attached file [vaniwaar@vaniwaar-w2k ~]$ g++-3.2 -c jj.C jj.C: In function `void __static_initialization_and_destruction_0(int, int)': jj.C:29675: Internal compiler error in find_function_data, at function.c:329 Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions. Release: g++-3.2 (GCC) 3.2 Environment: RH Linux 7.3 How-To-Repeat: Simply compile the attached file
Fix: Please! :-)
State-Changed-From-To: open->analyzed State-Changed-Why: Confirmed. The bug can be demonstrated with the following code snippet: ----------------------------snip here-------------------------- class A { static char* p; }; int i = 1; char* A::p = new char[i]; class B { B(); }; B::B() {} ----------------------------snip here-------------------------- This crashes gcc 3.0.x, 3.1 - 3.2.1, and mainline (just compile with g++ -c) - with gcc 2.95.x, however, the code compiles fine. So this is a regression from 2.95.x. A workaround is to write "new char[1]" instead of "new char[i]" (i.e. replace line 29675 by char* SpParmSetDataItem::ret = new char[30]; in the file jj.C).

I'd be happy to close it, but we need agreement that it will not be fixed on 3.2 any more (where it is a regression as well). I have adapted the synposis in the meantime, to reflect this. Jason, you wrote the fix. Is there any chance of rolling it over to the branch, or is this too invasive?

Its "sibling" PR 7473 has already been closed and it seems this bug was fixed some time ago, too. The ChangeLog entry for the fix is in cp/ChangeLog, so maybe it was not recognised by the "cvs commit" machinery?? Greetz Steven
State-Changed-From-To: analyzed->closed State-Changed-Why: Fixed for 3.3 and mainline; 3.2 branch is now closed.
(In reply to comment #7) > * init.c ... > (build_new_1): ... Use an incomplete array type for full_type. This change has caused PR c++/20427. The following variant of the reduced testcase also changed from ICE to wrong-code: struct A { static char* p; }; int i = 1; char* A::p = new char[i] (); void foo() {}
