By the way, I will eventually get back to checking and merging your pull requests. I have not had the time to work on it recently.

I don't think any of the traces prior to the segfault are meaningful. The location is being used to store client data for a tile record. The j->deviceList in ResNewSDDevice() is just some random number that happens to be at that location. Usually "Bad Device location" means that magic got confused during the resistance extraction.

dlmiles · 2024-11-10T17:10:18Z

It is the value of j (not j->deviceList) that is the issue.
The value is 0xc000000000000004 which comes from TiSetClient(newtile, CLIENTDEFAULT); this is the value of MINFINITY or related data value #define INFINITY ((1 << (8*sizeof (int) - 2)) - 4) which is a value of bffffffffffffffc

Which works out (for MINFINITY in the negative form) like perl -e 'printf "%x\n", -((1 << (8*8 - 2)) - 4);' for a result of c000000000000004

The traces show the specific memory location (of a Tile*) having its ti_client changed a few times during the procedures of the TCL script. With the last time before the crash being from DBResetTilePlane()

Sorry, I don't have enough time to look at this in enough detail to make decently informed statements about it. But the basic underlying issue appears to be that ExtResetTiles() was called from ResExtractNet() to remove all the "tileJunk" client data records from the tiles in the database, but then ResExtractNet() continued to process tiles. Checking for CLIENTDEFAULT would be a quick way to stop the segfaulting, but the underlying problem needs to be sorted out. I think the error always happens after a "Bad Device Location" error message has been printed, which probably indicates the problem that sets up the chain or errors ending with the segfault.

Thanks Tim for the feedback.

The following patch allows the extresist proc to complete. There are a number (10) of "Bad Device" warnings over the design. Investigating why will be for another day but at least this issue records the scenario via a project.

If a version of this patch was to be used, should the extresist proc return an error status, if 1 or more Bad Device warning(s) are emitted. Then maybe an option to extresist -ignore_bad_devices to mitigate that error status into a success status, still reporting.
Then the error status is given it would emit a print/log entry informing the user of the number of bad devices being non-zero as the cause of the error and the availability of the ignore option to mitigate it.

This is just so scripts by default will continue to fail. Previously they failed via SIGSEGV now they will fail gracefully via proc error status.

I applied this patch to magic version 8.3.509. I suggest leaving the issue open until the underlying "Bad Device" error is resolved.

error in "extresist". The underlying error still exists and causes a "Bad Device" error but no longer crashes magic. See github Issue #353.

but also design triggers tg_Tdi=-1 which has an ASSERT at the top of ResWriteExtFile(), this log output logs the ASSERT was triggered but continues as if asserts disabled

RTimothyEdwards added a commit that referenced this issue Dec 27, 2024

Applied patch from Darryl Miles that prevents a segfault on an

f80540a

error in "extresist". The underlying error still exists and causes a "Bad Device" error but no longer crashes magic. See github Issue #353.
