--- Comment #7 from Aurryon Schwartz <social@staraurryon.com> ---
Good evening everyone,

I'm having the same problem as mentioned and disabling glvnd in the build
process prevented the segfault during the loading time of DL.

Here are my specs:
- Radeon WX 3100
- Vega 64 (used with DRI_PRIME env)
- Ubuntu 18.10

Glxinfo:

OpenGL renderer string: Radeon RX Vega (VEGA10, DRM 3.27.0,
4.19.4-041904-lowlatency, LLVM 8.0.0)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 19.0.0-devel -
padoka PPA
OpenGL core profile shading language version string: 4.50

Default Ubuntu 18.10 compile flags:
staraurryon@Aurryon-Desktop:~$ dpkg-buildflags 
CFLAGS=-g -O2 -fdebug-prefix-map=/home/staraurryon=. -fstack-protector-strong
-Wformat -Werror=format-security
CPPFLAGS=-Wdate-time -D_FORTIFY_SOURCE=2
CXXFLAGS=-g -O2 -fdebug-prefix-map=/home/staraurryon=. -fstack-protector-strong
-Wformat -Werror=format-security
FCFLAGS=-g -O2 -fdebug-prefix-map=/home/staraurryon=. -fstack-protector-strong
FFLAGS=-g -O2 -fdebug-prefix-map=/home/staraurryon=. -fstack-protector-strong
GCJFLAGS=-g -O2 -fdebug-prefix-map=/home/staraurryon=. -fstack-protector-strong
LDFLAGS=-Wl,-Bsymbolic-functions -Wl,-z,relro
OBJCFLAGS=-g -O2 -fdebug-prefix-map=/home/staraurryon=.
-fstack-protector-strong -Wformat -Werror=format-security
OBJCXXFLAGS=-g -O2 -fdebug-prefix-map=/home/staraurryon=.
-fstack-protector-strong -Wformat -Werror=format-security

Additional build flags in debian/rules:
ifeq (,$(filter $(DEB_HOST_ARCH), armhf sh3 sh4))
buildflags = \
        $(shell DEB_CFLAGS_MAINT_APPEND=-Wall DEB_CXXFLAGS_MAINT_APPEND=-Wall
dpkg-buildflags --export=configure)
else
  ifneq (,$(filter $(DEB_HOST_ARCH), armhf))
  # Workaround for a variant of LP: #725126
  buildflags = \
        $(shell DEB_CFLAGS_MAINT_APPEND="-Wall -fno-optimize-sibling-calls"
DEB_CXXFLAGS_MAINT_APPEND="-Wall -fno-optimize-sibling-calls" dpkg-buildflags
--export=configure)
  else
  # Workaround for https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83143
  buildflags = \
        $(shell DEB_CFLAGS_MAINT_APPEND="-Wall -O1"
DEB_CXXFLAGS_MAINT_APPEND="-Wall -O1" dpkg-buildflags --export=configure)
  endif
endif

I also tried to disable -Wl,-Bsymbolic-functions but without success as it was
not mentioned in RedHat build documentation.

If you have any comment on my infos, please don't hesitate.
I have started to investigate Fedora build flags as @Timothy Arceri mentioned
that there was no issue in Fedora.

GL HF

Regards,
Aurryon
