[Reproducible-builds] Bug#785511: parser: FTBFS with g++-4.9: ... operator new(std::size_t) ... has a different exception specifier

[Chris West (Faux)]

Source: parser
Severity: serious
Justification: fails to build from source (but built successfully in the past)

operator new appears to have a different signature in g++-4.9's stdlib implementation,
which breaks the compilation of pa_pool.C / pa_memory.h.

Same problem in new[], delete, etc.
