I also got rid of the problem by the following code change.
I introduced two new temporary variables and avoided putting the two
<<"SRC" expressions (and a regexp) together in one single if-expression.

Does his help understanding the problem?

old code:
----------------------------------------------------------------------
     if try_compile(<<"SRC", opt, &b) or (/\A\w+\z/n =~ type && try_compile(<<"SRC", opt, &b))
#{COMMON_HEADERS}
#{header}
/*top*/
static #{type} t;
SRC
#{COMMON_HEADERS}
#{header}
/*top*/
static #{type} *t;
SRC
----------------------------------------------------------------------

new code:
----------------------------------------------------------------------
     src1 = <<"SRC"
#{COMMON_HEADERS}
#{header}
/*top*/
static #{type} t;
SRC
     src2 = <<"SRC"
#{COMMON_HEADERS}
#{header}
/*top*/
static #{type} *t;
SRC
     if try_compile(src1, opt, &b) or (/\A\w+\z/n =~ type && try_compile(src2, opt, &b))
----------------------------------------------------------------------
