Dear readers, Recently I upgraded my machine to Trisquel 5.5 (x86_64).
While I used Trisquel 5, I had no issues compiling guile, however now it appears all hell broke losoe. When compiling I get to the generation stage of GEN guile-procedures.texi. The stage ends up with a Segmentation fault. I have been debugging the lt_guile process with gdb, and some interesting things happened. The process received SIGPWR and SIGXCPU signals (in a loop), and eventually ends up with a SIGSEGV message from the procedure: GC_generic_malloc_inner. I ended up attempting to build the bdw-gc from scratch and link in the 7.1 stable version, but resulting in the same situation. I have no idea where the problem initiates, as it appears to be happening in a certain time interval (probably thread switching) and there is no way to pinpoint the problem in scheme itself. Even just looping around generates this error. Now, when I went through the make output I noticed some interesting things while compiling libguile_2.2_la-weak-table.lo: weak-table.c: In function 'move_disappearing_links': weak-table.c:164:7: warning: passing argument 1 of 'GC_unregister_disappearing_link' from incompatible pointer type [enabled by default] /usr/local/include/gc/gc.h:771:12: note: expected 'void **' but argument is of type 'scm_t_bits *' weak-table.c:165:7: warning: passing argument 1 of 'GC_general_register_disappearing_link' from incompatible pointer type [enabled by default] /usr/local/include/gc/gc.h:744:12: note: expected 'void **' but argument is of type 'scm_t_bits *' weak-table.c:175:7: warning: passing argument 1 of 'GC_unregister_disappearing_link' from incompatible pointer type [enabled by default] /usr/local/include/gc/gc.h:771:12: note: expected 'void **' but argument is of type 'scm_t_bits *' weak-table.c:176:7: warning: passing argument 1 of 'GC_general_register_disappearing_link' from incompatible pointer type [enabled by default] /usr/local/include/gc/gc.h:744:12: note: expected 'void **' but argument is of type 'scm_t_bits *' And although perhaps less important, when compiling libguile_2.2_la-gc.lo: gc.c:212:1: warning: 'GC_get_free_space_divisor' defined but not used [-Wunused-function] As I can't see anyone (yet) having this problem, I consider it might be rather unique, but I really would like to know what possibly could be going wrong and where I should start debugging.
