Log of failing rt_trap_exceptions_drt_gdb run

After we updated our gdb package from 11.2 to 12.1, the rt_trap_exceptions_drt_gdb test started to fail [1]. I've attached the full log for this test, but the gist is that the gdb backtrace

> #5  0x0000000000437709 in _Dmain (args=...) at src/rt_trap_exceptions_drt.d:9
doesn't match the grep

> grep "in D main (args=...) at .*rt_trap_exceptions_drt.d:9" > /dev/null < ./generated/linux/release/64/rt_trap_exceptions_drt_gdb.output
anymore, so the test fails.


Our workaround is to patch the grep expression in test/exceptions/Makefile to look for _Dmain instead [2], but I don't think that would work with older gdb versions.
