Bug ID: 108198
Summary: G++ fails to compile large 2D array initializer.
Product: gcc
Version: 12.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: filip.rak81 at gmail dot com
Target Milestone: ---
Created attachment 54148
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=54148&action=edit
Preprocessed output.
The following code (containing 2048x10 array initialization):
#define ROW { { 0.0, 0.0 }, { 1.0, 1.0 }, { 2.0, 2.0 }, { 3.0, 3.0 },
{ 4.0, 4.0 }, \
{ 5.0, 5.0 }, { 6.0, 6.0 }, { 7.0, 7.0 }, { 8.0, 8.0 }, { 9.0,
9.0 } }
#define ROW8 ROW, ROW, ROW, ROW, ROW, ROW, ROW, ROW
#define ROW64 ROW8, ROW8, ROW8, ROW8, ROW8, ROW8, ROW8, ROW8
#define ROW512 ROW64, ROW64, ROW64, ROW64, ROW64, ROW64, ROW64, ROW64
#define ROW4096 ROW512, ROW512, ROW512, ROW512, ROW512, ROW512, ROW512,
ROW512
template <typename T>
class cplx_t {
public:
T m_re;
T m_im;
cplx_t() : m_re(), m_im() {
}
cplx_t(const T& re, const T& im) : m_re(re), m_im(im) {
}
};
cplx_t<double> test_arr[2048][10] = {
ROW512, ROW512, ROW512, ROW512
};
int main() {
}
causes compiler to abort compilation without any error message.
