Hi, I created this debian PR earlier today: Bug#977223: Acknowledgement (guile-3.0: FTBFS on hppa - segmentation faults)
In the above, the segmentation fault occurs during exception handling on hppa. The exception is more or less handled on powerpc: ../meta/build-env \ guild compile --target="powerpc-unknown-linux-gnu" \ -W0 -O1 \ -L "/<<PKGBUILDDIR>>/module" \ -L "/<<PKGBUILDDIR>>/guile-readline" \ -o "language/tree-il/compile-cps.go" "../module/language/tree-il/compile-cps.scm" Backtrace: 11 (_ #<procedure efa84650 at ice-9/eval.scm:330:13 ()> # #) 10 (apply-smob/0 #<thunk efa7cba0>) In ice-9/eval.scm: 657:8 9 (_ #(#(#f) ("prompt") #<procedure efacfcb0 at ice-9/?> ?)) 619:8 8 (_ #(#(#<directory (guile-user) f00566e0>))) 155:9 7 (_ #(#(#<directory (guild) efe0daa0> ("compile" # ?)) #)) 619:8 6 (_ #(#(#<directory (srfi srfi-1) efcc4780> #<proc?> ?) ?)) 163:9 5 (_ #(#(#<directory (scripts compile) ef13ae60> "p?" ?) ?))
