Description of problem: An internal compiler error is encountered when compiling certain snippets of code. This appears to be an upstream bug. Version-Release number of selected component (if applicable): 9.2.1-2.3.el8 How reproducible: 100% Steps to Reproduce: 1. Install the gcc-toolset-9-gcc package 2. Get the gcc test case by running: $ wget -Opr96935.c 'https://gcc.gnu.org/git/?p=gcc.git;a=blob_plain;f=gcc/testsuite/gcc.dg/format/pr96935.c;h=c31109704be67ff539493acf73a6f4ca89ffff9f;hb=d01c3def63caf59d1d156aec8d52a1540e5ffe27' 3. Enable the toolset GCC with command: $ . /opt/rh/gcc-toolset-9/enable 4. Compile the test case with "gcc -c -O pr96935.c". Actual results: Compile fails with the following error message: --- during GIMPLE pass: printf-return-value pr96935.c: In function ‘foo’: pr96935.c:6:1: internal compiler error: in subspan, at input.h:68 --- Expected results: Successful compilation. Additional info: - Bug is also present on gcc-toolset-10-gcc-10.2.1-2.el8.x86_64. - There is a patch at the following commit address: https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=d01c3def63caf59d1d156aec8d52a1540e5ffe27
This happens with gcc-toolset-10 too.
Already fixed in the latest gcc-toolset-10-gcc.
