3 months ago Two new situations: Enabling enable-devel-all or enable-devel-logging causes make bug Configure with enable-devel-all or enable-devel-logging can eliminate the fault??
After cloning the latest source code from git 1. When trying to use: ./configure --enable-devel-all or ./configure --enable-devel-logging Must also include --enable-pixman, otherwise make error
./configure --enable-devel-all
make clean all
...

make: *** [Makefile:443: all] Error 22. When trying to use ./configure --enable-devel-all or enable-devel-logging + --enable-pixman +any Make is successful --enable-devel will result in a significant performance decrease in video decoding But changing the session screen resolution on the client side rapidly will not cause any anomalies!!
If ignore enable-devel-all or enable-devel-logging keeping other switches, the fault will reappear:
client use /gfx /gfx:avc420 /gfx:avc444 /nsc rapidly changing the session screen resolution or switch full screen with window ,
will cause the server session to crash, the client connection to disconnect.
and normal usage after the client reconnects.

Steps to reproduce
Low-intensity use screen dynamic-resolution sometimes results in crashes.
found a reproducible method: kernel: traps: xrdp[13310] general protection fault ip:7fab1ca41e3a sp:7fffd62f3fd0 error:0 in libc.so.6 xrdp[525]: [ERROR] Child 13048 terminated unexpectedly with signal SIGSEGV
Connect session using freerdp + dynamic-resolution - default is 1024x768 windows.
mouse double-click on the session window to enlarge it. Repeat clicking to reduce the window back to its original size.
Rapidly repeat the process of enlarging and reducing the window 10 to 30 times(mouse clicking >3 times per second), causing the XRDP server to crash.
Possibly related to the video module. Decoding that triggers a crash: freerdp + dynamic-resolution /gfx or /gfx:avc420 /gfx:avc444 /nsc Enlarging and reducing 100 times did not trigger the crash??: freerdp + dynamic-resolution /rfx
--In addition, sometimes dynamic-resolution session window will freeze after being minimized and waiting for several tens of minutes. unknown whether this issue is related to the previous problem?
If needed, please tell me how to conduct further tests.
✔️ Expected Behavior
client use screen dynamic-resolution not cause crash.
❌ Actual Behavior
/rfx normal
/gfx:avc420 /gfx /nsc terminated unexpectedly with signal SIGSEGV
