Bug ID: 96387
Summary: gnu gmp c source edit g++ internal compiler error
appear
Product: gcc
Version: 9.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: cents2823 at yahoo dot co.jp
Target Milestone: ---
Gnu gmp c source edit and configure, make, make check, make install.
Modified link change to enable gnu gmp executive.
(ln -nfs /usr/local/lib/libgmp.so.10.4.0
/usr/lib/x86_64-linux-gnu/libgmp.so.10)
I get the following gcc error. G++ compilation is normal before link change.
As shown in #3, the same error occurs even if G++ uninstall install.
Therefore, it seems that the cause is that the data referenced by g++ has
changed. Where is the data referenced by gcc?
Gnu gmp changes are shown in #4. This change is necessary to make the integer
more than 40 billion digits.
#5 shows g++ -v.
Thanking you in advance.
