While installing /usr/pkgsrc/emulators/simh from package source an 
internal compiler error occurs while compiling pdp11_dc.c.

$ gcc -std=c99 -U__STRICT_ANSI__ -g -O2 pdp11_dc_compiler_error_pp.c
PDP11/pdp11_dc_compiler_error.c: In function 'dcx_wr':
PDP11/pdp11_dc_compiler_error.c:324: internal compiler error: in 
change_address_1, at emit-rtl.c:1819
Please submit a full bug report,
with preprocessed source if appropriate.

pdp11_dc_compiler_error_pp.c is pdp11_dc.c with all functions except dcx_wr
removed and then run through the cpp.

pdp11_dc_compiler_error_pp.c is available upon request.
