Does gdb works on ppc32 for big c++ programs?

Randrianasulu commented 2 years ago

System

qemu-system-ppc -M mac99 with either G3 or G4 (default) cpu

xuname:
command not found
package:
affected package(s) including the version: pkgver gdb 11.1_2

Expected behavior

gdb debug program

Actual behavior

gdb bin/cin aborts without even showing splashscreen of program (visible on normal run)

Steps to reproduce the behavior

try to compile big c++ program (I used cinelerra-gg {0} with some patches)

in my case program failed to start fully (segfault somewhere in theme initialization) so I tried to debug this and got gdb abort. enabling core dumping with ulimit sadly produced core gdb can't read. But even core produced by gdb's own abort can't be read, new abort!

valgrind also does not work.

{0} - https://git.cinelerra-gg.org/git/?p=goodguy/cinelerra.git;a=summary with some patches not yet upstream

i tied to capture gdb's output into file but apparently some control esc symbols made viewing even this short file fun... (cat does not show them, mcview does)

configure line for cinelerra-gg I used (because some switches do not work yet)

$ ./configure --with-single-user --disable-static-build --without-lv2 --without-vaapi --without-vdpau --without-dv --without-firewire --without-thirdparty
