Do you really need to pass e.g. -g to LDFLAGS?
I tried this in my jhbuildrc:
module_extra_env = {
'epiphany': {'CFLAGS': '-fno-omit-frame-pointer -fno-optimize-sibling-calls
-fno-common -fsanitize=address -U_FORTIFY_SOURCE',
'LDFLAGS': '-fno-common -fsanitize=address -U_FORTIFY_SOURCE
-Wl,-z,lazy',
'ASAN_OPTIONS': 'log_path=/home/mcatanzaro/asan-error'
}
}
But it doesn't work for Epiphany, the web extension is broken:
Error loading module
'/home/mcatanzaro/src/jhbuild/install/lib/epiphany/web-
extensions/libephywebextension.so':
/home/mcatanzaro/src/jhbuild/install/lib/epiphany/libephymisc.so:
undefined symbol: __asan_option_detect_stack_use_after_return
Is anything special needed for dlopened modules?
I'm pretty sure I had it working in the past as I did use asan once
before to fix some miscellaneous leaks, but I don't remember how I got
it to work. We should come up with some jhbuildrc foo that will work
without breaking modules.
