             Summary: Differences in gcc options cause the undefined sanitizer to fail in pjproject when using dev-mode
                 Key: ASTERISK-28622
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-28622
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Core/BuildSystem
    Affects Versions: 16.6.1, 13.29.1, 17.0.0
         Environment: Gcc 9.2.1
            Reporter: George Joseph
            Severity: Minor


When using dev-mode and the Undefined sanitizer, pjproject fails to link
the pjsua app and spits out thousands of errors in the libraries.  When using the Undefined sanitizer _without_ dev-mode, it works fine.  This may be due to the different options passed to the pjproject Makefile.  For reference here are 2 examples of the command lines.  We should probably do an audit on the options anyway, many of the options get passed to gcc multiple times.

With dev-mode:
{noformat}
gcc -c -Wall -DPJ_AUTOCONF=1 -pthread -pipe -g3 -fno-omit-frame-pointer -fsanitize=undefined 
-O3 -fno-partial-inlining -DPJ_IS_BIG_ENDIAN=0 -DPJ_IS_LITTLE_ENDIAN=1   
-fPIC -Wno-unused-but-set-variable -Wno-unused-variable -Wno-unused-label -Wno-unused-function -Wno-strict-aliasing -pthread -pipe -g3 -fno-omit-frame-pointer -fsanitize=undefined 
-O3 -fno-partial-inlining 
-fPIC -Wno-unused-but-set-variable -Wno-unused-variable -Wno-unused-label -Wno-unused-function -Wno-strict-aliasing -I../include -I../../pjlib/include -I../../pjlib-util/include -I../../pjnath/include -I../../pjmedia/include             \
