Subject: c++/6971: Internal compiler error / compiler SIGSEGV
Date: Sat, 08 Jun 2002 12:26:00 -0000 [thread overview]
Message-ID: <20020608192018.13738.qmail@sources.redhat.com> (raw)
>Number: 6971
>Category: c++
>Synopsis: Internal compiler error / compiler SIGSEGV
>Confidential: no
>Severity: serious
>Priority: medium
>Responsible: unassigned
>State: open
>Class: sw-bug

Linux / i686
>Description:
Compiling the test code (as attached), the compiler
reports an internal compiler error or crashes:
Removing TONS of code to get a minimal example made the
SIGSEGVs vanish; the internal errors remaining:
gcc -c crashme.cc -Wno-non-template-friend -DBUG=0
crashme.cc: In function `void internal_vect::mult_mv(internal_vect::vector<r>&,
const internal_vect::matrix<r, c>&, const
internal_vect::vector<c>&) [with int r = 10,
int c = 10, int N = 3]':
crashme.cc:53: instantiated from `void
vect::operator*=(vect::Vector<R>&, const
vect::Matrix<N, N>&) [with int N = 10]'
crashme.cc:89: instantiated from here
crashme.cc:37: Internal compiler error in c_expand_expr,
at c-common.c:3650
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
Similar thing with
gcc -c crashme.cc -Wno-non-template-friend -DBUG=1
(Please don't tell me that I shall make the demo code
even shorter. I already spent two hours or more to strip
it down to that size; removing any individual line will
prevent the bug from showing up.)
>How-To-Repeat:
Compile example code (as attached)
>Fix:
Don't know.
