Attempting to run fvwm on a x61/965gm with xserver 1.21.1 with the modesetting driver on OpenBSD/amd64 would cause the xserver to reliably crash. I tracked this down to the free() calls introduced in2906ee5e4a(d1ca47e124in branch). clang also warns about this: glamor_program.c:296:13: warning: variable 'vs_prog_string' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized] glamor_program.c:290:9: warning: variable 'vs_prog_string' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized] glamor_program.c:288:9: warning: variable 'vs_prog_string' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized] glamor_program.c:277:13: warning: variable 'vs_prog_string' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized] glamor_program.c:296:13: warning: variable 'fs_prog_string' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized] glamor_program.c:290:9: warning: variable 'fs_prog_string' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized] glamor_program.c:288:9: warning: variable 'fs_prog_string' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized] glamor_program.c:277:13: warning: variable 'fs_prog_string' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized] Signed-off-by: Jonathan Gray <jsg@jsg.id.au> Reviewed-by: Olivier Fourdan <ofourdan@redhat.com> Fixes:2906ee5e4("glamor: Fix leak in glamor_build_program()") (cherry picked from commit5ac6319776)
