Bug ID: 105182
   Summary: compiling NJOY21 causes a ICE segmentation fault: 11
   Product: gcc
   Version: 11.1.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: fortran
  Assignee: unassigned at gcc dot gnu.org
  Reporter: kermitnuc at gmail dot com
  Target Milestone: ---

GCC 10.3 compiles NJOY21 without issue.  GCC 11.1 and 11.2 do not.  

GCC configure script:
/configure  --prefix=/usr/local/gcc-1030 --enable-languages=c,c++,fortran,lto
CC=/usr/bin/gcc CXX=/usr/bin/g++ LD=/usr/bin/ld  --with-gmp=/usr/local
--with-mpfr=/usr/local  --with-mpc=/usr/local --with-isl=/usr/local
--with-libiconv-prefix=/usr/local --with-libiconv=/usr/local --with-system-zlib
--with-native-system-header-dir=/usr/include --build=x86_64-apple-darwin21.4.0 
CXXFLAGS="-I/usr/local/include " CCFLAGS="-I/usr/local/include " 
LDFLAGS="-L/usr/local/lib " CPPFLAGS="-I/usr/local/include " --enable-libatomic
--enable-libgomp --enable-libitm --enable-libquadmath
--enable-libquadmath-support -enable-shared --enable-shared-libgcc
--enable-static --enable-version-specific-runtime-libs
--with-sysroot=/Library/Developer/CommandLineTools/SDKs/MacOSX12.3.sdk 

Similar for 11.1 and 11.2.
Using XCODE 13 on MacOS 12.3.1

NJOY21 is available at:  https://www.njoy21.io
The error when compiling the ERRORR.F90 subroutine.

NJOY configure script:
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_VERBOSE_MAKEFILE:BOOL=TRUE -D
CMAKE_CXX_COMPILER=/usr/local/gcc-1120/bin/x86_64-apple-darwin21.4.0-c++ -D
CMAKE_Fortran_COMPILER=/usr/local/gcc-1120/bin/x86_64-apple-darwin21.4.0-gfortran

If one comments out these lines in subroutine resprx:
 !--Unresolved
 if (lru.eq.2) then
call rpxunr(a,amur,mxlru2,iest,ieed,nwscr)
 !--Resolved with sammy method
 else if (nmtres.gt.0) then
call rpxsamm(nwscr,a,ier)
 !--Resolved with errorj method
 else
if (lcomp.eq.0) then
   call rpxlc0(nwscr,a)
else if (lcomp.eq.1.or.lcomp.eq.2) then
   call rpxlc12(nwscr,a,iest,ieed)
endif
 endif

Then error.f90 will compile.
Is there a limit to how many subroutine calls are allowed?

This subroutine compiles when GCC 10.3 is used.  What was changed for 11.1 that
might impact this?

Is there a compiler option that I can use to provide more information to you?

I ran the stack size up to ~64Mb.

I can compile MCNP which is much bigger.
Again, 10.3 compiled it with a stack size of 8 Mb.

The latest GIT pull fixed the issue
