>Description:
The testcase below, distilled from Mesa 4.0.2 (si-glu/libnurbs/nurbtess/quicksort.cc), ICEs in current gcc-3.1-branch. This is a regression from gcc-3.0.4.
[gb@kernel gcc]$ ./cc1plus -O1 -finline-functions ~/vrac/qsort.cpp
void f() void g() void f() void g()
/home/gb/vrac/qsort.cpp:11: Internal compiler error in genrtl_finish_function,
at cp/semantics.c:2622
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
>How-To-Repeat:
Compile the following testcase with -O1 -finline-functions and the current gcc-3.1-branch.
[gb@kernel gb]$ cat ~/vrac/qsort.cpp
static void g();
void f()
{
void g();
g();
}
void g()
{
}
BTW, do you want the full preprocessed source from Mesa?
>Fix:
Either don't use inlining or remove the declaration of g() in f().
Ah, as I happen to have a few prebuilt CVS snapshots around, the following might help to spot of the regressing change.
1) It works with
GNU C++ version 3.1 20020315 (prerelease) (i686-pc-linux-gnu)
2) But fails as above-mentioned with
GNU C++ version 3.1 20020316 (prerelease) (i686-pc-linux-gnu)
