Old Synopsis: internal error and segmentation fault of gcc 3.2
New Synopsis: [3.2/3.3/3.4 regression] ICE in write_expression on invalid function prototype
State-Changed-From-To: open->analyzed
State-Changed-By: bangerth
State-Changed-When: Tue Feb 18 22:14:52 2003
State-Changed-Why:
Confirmed. A regression in the C++ front end introduced
between 2.95 and 3.0 that is still there in mainline of
yesterday, as well as (of course) in 3.2.2 and 3.3.
Reduced code is
----------------------
void foo(double a[][2]);
void bar() {
int nx = 2;
void foo(double a[][nx]);
foo(0);
}
-----------------------------
tmp/g> /home/bangerth/bin/gcc-3.4-pre/bin/gcc -c x.cc
x.cc: In function `void bar()':
x.cc:6: internal compiler error: Segmentation fault
Please submit a full bug report,
It ICEs here:
