[patchv2] compile: Fix crash on cv-qualified self-reference https://sourceware.org/ml/gdb-patches/2015-05/msg00434.html Message-ID: <20150516132555.GB17266@host1.jankratochvil.net> compile code struct_object.selffield = &struct_object ./compile/compile-c-types.c:83: internal-error: insert_type: Assertion `add == NULL || add->gcc_type == gcc_type' failed. A problem internal to GDB has been detected, Fix+testcase is in the mail. This is not a regression.
This PR will be fixed in GCC: https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;a=commitdiff;h=072dfdba0ea62abb65514cb3a90cdf3868efe286
