Collecting various links and snippets to make this easier for me to analyze.

Now that v1.4.4 is on CRAN, there is a new deadline to address this issue: "Please correct before 2025-03-14 to safely retain your package on CRAN."

gcc-UBSAN result from CRAN's additional issues, pertaining to readxl v1.4.3

https://www.stats.ox.ac.uk/pub/bdr/memtests/gcc-UBSAN/readxl/

First instance reported in examples for excel_sheets(). Perhaps notably the geometry.xls sheet has been accessed earlier (in the examples for cell-specification) w/o issue. Not sure how much to read into where the warning appears in this output, though.

Key bits:

libxls/xls.c:583:51: runtime error: index 1 out of bounds for type '<unknown> [1]'
libxls/xls.c:584:58: runtime error: index 1 out of bounds for type '<unknown> [1]'
libxls/xls.c:481:75: runtime error: index 1 out of bounds for type 'BYTE [1]'

gcc-san result from "specialChecks" on CRAN's incoming checks for a submission of (hopeful) readxl v1.4.4

Implicates the same loci in xls.c as gcc-UBSAN report for readxl v1.4.3, plus a couple other locations in that file.

https://win-builder.r-project.org/incoming_pretest/readxl_1.4.4_20250226_040323/specialChecks/gcc-san/

From summary.txt:

Package check result: OK

Post-processing issues found:

valgrind result seen in my recent PR updating libxls to v1.6.3

https://github.com/tidyverse/readxl/actions/runs/13274947484/job/37062619489

Suspect this is unrelated to the libxls out of bounds warnings

I think this is a bug in libxls. Posted it here: libxls/libxls#144 (we fixed the same problem in mongo-c-driver last week)

Yeah I already started investigating such a solution yesterday in this branch: https://github.com/tidyverse/readxl/compare/fix-sanitizer-warning. I made 1 interesting commit there (after faffing about with GHA) that made some of the warnings go away (it's coming from multiple locations).

There is relevant history around readxl and libxls here: libxls/libxls#15.

Ah sorry didn't mean to cross you! Seems like we found the same solution, which is a good sign :)

Brief recap of some history, now that I've re-uploaded all of this into my head. I may or may not return to add more links to specific resources or refs.

  • libxls has historically used flexible array members (FAMs) in structs such as MULRK (see https://github.com/libxls/libxls/blame/811408fa031f2f0c1a2e6612bf58dc64bea6d450/include/libxls/xlsstruct.h#L190-L200)
  • FAMs are valid constructs for C but not for C++ (see Compatibility of C and C++)
  • This presents problems for readxl, which requires the use of a C++ compiler, including for the C code
  • Historically, readxl had patches in which FAMs were artificially declared to have fixed length, usually (always?) length 1
  • At some point, these pragmatic patches became incompatible with other changes happening in libxls
  • In an ideal world, libxls could be modified to not use FAMs, but no one has the motivation or bandwidth to do this, yet we all want libxls to be C++ compatible
  • Several years ago libxls basically adopted readxl's polite fiction re: the FAMs, along with other necessary changes (see Zero size arrays and flexible array members libxls/libxls#15 and libxls/libxls@b3fed3c)
  • That state has recently become untenable, due to increased strict sanitizer checks by CRAN
  • The fix for this issue is the latest instalment in this long-running sequence of adaptations aimed at keeping readxl compliant with CRAN's requirements, even as libxls still (effectively) uses FAMs
