Tested with 3 gcc versions:
seb@myp233:~/test/cp$ gcc-2.95 -v
Reading specs from /usr/lib/gcc-lib/i386-linux/2.95.4/specs
gcc version 2.95.4 20011002 (Debian prerelease)
seb@myp233:~/test/cp$ gcc-3.0 -v
Reading specs from /usr/lib/gcc-lib/i386-linux/3.0.4/specs
Configured with: ../src/configure -v --enable-languages=c,c++,java,f77,objc --prefix=/usr --infodir=/share/info --mandir=/share/man --enable-shared --with-gnu-as --with-gnu-ld --with-system-zlib --enable-long-long --enable-nls --without-included-gettext --disable-checking --enable-threads=posix --enable-java-gc=boehm --with-cpp-install-dir=bin --enable-objc-gc i386-linux
Thread model: posix
gcc version 3.0.4
seb@myp233:~/test/cp$ gcc-3.2 -v
Reading specs from /usr/lib/gcc-lib/i386-linux/3.2.1/specs
Configured with: /mnt/data/gcc-3.1/gcc-3.2-3.2.1ds2/src/configure -v --enable-languages=c,c++,java,f77,proto,objc,ada --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --with-gxx-include-dir=/usr/include/c++/3.2 --enable-shared --with-system-zlib --enable-nls --without-included-gettext --enable-java-gc=boehm --enable-objc-gc i386-linux
Thread model: posix
gcc version 3.2.1 20020924 (Debian prerelease)
Results for the original bug example:
seb@myp233:~/test/cp$ gcc-2.95 -c pr7679.cc
pr7679.cc: In method `double receptors::occupancy(int)':
pr7679.cc:14: parse error before `;'
Stops shortly.
seb@myp233:~/test/cp$ gcc-3.0 -c pr7679.cc
pr7679.cc: In member function `double receptors::occupancy(int)':
pr7679.cc:14: parse error before `;' token
Loops indefinitely.
seb@myp233:~/test/cp$ gcc-3.2 -c pr7679.cc
pr7679.cc: In member function `double receptors::occupancy(int)':
pr7679.cc:14: parse error before `;' token
Loops indefinitely.
Also tested:
struct f
{
int oo()
{
return (2;
}
};
Slightly simpler to analyse than the original bug example,
and produces the same infinite loop.
Note that gcc-3.2 stops correctly when it gets only the function declaration:
int oo()
{
return (2;
}

>Description:
When I try to compile the code bellow using the command g++ teste.cpp the compiler crashes if one parentesis is missing in the end of the definition of the function double occupancy(int m).
>How-To-Repeat:
Compile the program below using g++. There is a missing parentesis in the end
of the line
{return L/(L+Ka*activity(m,1,activity())+Ki*(1-activity(m,1,activity()));}
that make the compiler crash.
const int n_methyl=2;
const double tiny=1e-10;
class receptors
{
public:
static double C,E[n_methyl][2],Ka,Ki,L,fm[n_methyl];
double x[10];
receptors(){};
double activity() {return x[0];}
double activity(int,int,double);
double occupancy(int m)
{return L/(L+Ka*activity(m,1,activity())+Ki*(1-activity(m,1,activity()));}
double occupancy()
{double s=0; for(int m=0;m!=n_methyl;m++)s+=occupancy(m)*fm[m]; return s;}
double methylation()
{double s=0;for(int m=0;m!=n_methyl;m++) s+=m*fm[m]; return s;}
void tune_fm(double);
double show();
