Description of problem: When GCC was introduced to Fedora, gcl stopped building successfully on s390x. The attempt to dump to raw_pre_gcl failed. GDB work showed nonsensical results. We were attempting to read a Lisp file, and the variable c, which should have been the value of reading a character from the file, somehow held a character table instead. Turning the optimization level down to -O1 got past this stage, but then failed later like this: Loading binary of GCL_PCL_PKG... ;; Loading #p"/builddir/build/BUILD/gcl-2.6.14/unixport/../pcl/gcl_pcl_pkg.o" mprotect failure: 0xbdb000 4096 : Permission denied Error: ERROR "The assertion !clear_protect_memory(memory) on line 615 of sfaslelf.c in function fasload failed: Invalid argument" Fast links are on: do (si::use-fast-links nil) for debugging ERROR "The assertion !clear_protect_memory(memory) on line 615 of sfaslelf.c in function fasload failed: Invalid argument" Broken at LOAD. Type :H for Help. 1 Return to top level. >>Signalled by LOAD. make[1]: *** [makefile:35: gcl_pcl_boot.c] Error 255 make[1]: Leaving directory '/builddir/build/BUILD/gcl-2.6.14/pcl' rm h/mcompdefs.h make: *** [makefile:90: unixport/saved_pcl_gcl] Error 2 Clearly something is still being miscompiled on s390x, even at optimization level 1. Whether the fault lies with GCC or with the gcl code remains to be determined. Version-Release number of selected component (if applicable): gcl-2.6.13-2.fc38.s390x gcc-13.0.1-0.1.fc38.s390x How reproducible: Always Steps to Reproduce: 1. Do a Rawhide build of gcl on s390x 2. 3. Actual results: The build fails. Expected results: Good build, as with gcc 12. Additional info:
This bug appears to have been reported against 'rawhide' during the Fedora Linux 38 development cycle. Changing version to 38.

This message is a reminder that Fedora Linux 38 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora Linux 38 on 2024-05-21.

Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora Linux 38 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora Linux, you are encouraged to change the 'version' to a later version prior to this bug being closed.
