Tested 15f4f87976493f6e144a9bdb5eb7f0109543a393: runtest gdb.fortran/dynamic-other-frame.exp [...] (gdb) bt^M #0 0x000000000040071d in bar_ ()^M #1 0x00000000004006c7 in foo (string=gdbtypes.c:2009: internal-error: dynamic_prop_get_const_val_ptr: Assertion `prop->kind == PROP_CONST' failed.^M A problem internal to GDB has been detected,^M Fedora {20,21} {x86_64,i686}: internal-error Fedora {21,21} x86_64 -m32: PASS But it depends on something suspicious, for a given build the testsuite results are stable but for builds done at different time / under different configurations the results differ. Could you first check-in the gdb.fortran/dynamic-other-frame.exp testcase to the Intel branch? I find it difficult to catch a crash of a testcase not even present in your repository. Thanks, Jan
