But when I compile it with -g, I cannot reproduce it from the shell or from gdb.

I compile groff and then run "sparc32 make" in the groff/doc source directory and it fails with: export GROFF_TMAC_PATH; \ sed -e "s;@VERSION@;`cat ../VERSION``sed -e 's/^0$//' -e 's/^[1-9].*$/.&/' ../RE VISION`;" pic.ms \ | ../src/roff/groff/groff -p -e -t -Tps -F../font -U -ms -mwww >pic.ps ../src/roff/groff/groff: troff: Illegal instruction All other input files works fine. Same for uic from qt2 and qt3: If I try to debug it, it works. And there are only a few input files for which it fails, most input files works fine.

It has to be dropping a core file somewhere, check that out with gdb. ^ permalink raw reply [flat|nested] 9+ messages in thread

After I run some testsuites to check for regressions I will update the GNATs entry for this bug and post the patch. I will add you to the CC: of the GNATs PR so that you will know when 3.1 CVS has the fix installed. It turns out to be a generic sparc backend bug. ^ permalink raw reply [flat|nested] 9+ messages in thread
