The attached testcase (simplified from gcc's limits.h usage) goes into an infinite loop with: $ synopsis -v -d -Wp,profile=1 -p C -I. -Ibaz foobar.c [snip] entering ASTTranslator::found_include_directive <foobar.h> leaving ASTTranslator::found_include_directive entering ASTTranslator::opened_include_file /tmp/i/bug/foobar.h(rel=./foobar.h) leaving ASTTranslator::opened_include_file entering ASTTranslator::found_include_directive <foobar.h> leaving ASTTranslator::found_include_directive entering ASTTranslator::opened_include_file /tmp/i/bug/foobar.h leaving ASTTranslator::opened_include_file /tmp/i/bug/foobar.h(3): fatal error: include files nested too deep: 1024 Error: CppError: /tmp/i/bug/foobar.h:3 : fatal error: include files nested too deep: 1024 gcc gives on this input: $ make gcc gcc -nostdinc -I. -Ibaz -E foobar.c # 1 "foobar.c" # 1 "<built-in>" # 1 "<command line>" # 1 "foobar.c" # 1 "foobar.h" 1 # 1 "./foobar.h" 1 # 1 "baz/foobar.h" 1 # 1 "baz/foobaz.h" 1 # 1 "./foobar.h" 1 # 4 "baz/foobaz.h" 2 # 6 "baz/foobar.h" 2 # 4 "./foobar.h" 2 # 4 "foobar.h" 2 # 2 "foobar.c" 2

I think that this is a bug in wave (tried 1.35.0 and IIRC 1.34.x).

As I can't reproduce this with current boost.wave versions (and of course, current Synopsis versions :-) ), I'm closing this issue.
